[teneo] eContainer is set null in inverseAdd() when adding new element into Resource's contentEList [message #83177] Fri, 11 May 2007 10:54 Go to next message

Hi,

In my EMF model , Product and ProductRegistry has many-To-one
relationship and ProductRegistry set as transient.

I create a new Product and set it's eContainer as not null
and then add this Product element into HibernateResourse's
contents, in inverseAdd() ,the eContainer is removed.

If I set the referenceFeature's proxyFlag as 65536 in debug mode
to make the isResolveProxy() return true, I could stop this removal.

Do I need to set something in hibernate.hbm.xml?

Anthony

Hi,
Is parent of the Product already present in the resource?

Anthony,

This sounds like expected behavior. For non-proxy resolving containment
reference (EReference.isResolveProxies == true), eContainer and
eDirectResource mutually exclusive, i.e., you can't have an EObject
container and be contained directly by a resource's getContents. Only
for proxy resolving containment is it possible to put a "child" in to a
separate resource. Note that if Products parent is already in a
resource then product.eResource() will be non-null, and there is no need
to put the Product directly in the resource since it's indirectly
contained in the resource by virtue of the parent being contained in a
resource.

Hi,
It is not.
I have to use another resource to init the parent to get it
as EMF owner object to create AddChild command.

It seems the saving action would fail since the parent is not in the
same resource, but if the eContainer is not removed then the element is
saved in DB.

Merks,

Thanks.

So if the container is set as transient, how to persist the
container's element ?

Anthony,

I'm not sure I completely follow what you are asking (container is set
as transient implies you don't want to serialize it), but in the XMI
serialization, to serialize a reference to the container, you need to
define a non-transient container feature (i.e., an EReference that's the
eOpposite of the containment feature).

Merks,

Actually I used Teneo to save my model into DB.

Let me introduce the picture:

When the first time the model is created , the only one
ProductRegistry element is created and saved.

And then when user click the Product node in UI, I need to
show a table to list the products.

Because the products collection could be really huge, so I choose
to change them to many-to-one's (so only persist the reference from the
child to the parent) and load the one-to-many relation (parent to child)
on demand through an explicit query (make the many-reference from the
parent to the child transient). Adding to the parent is then done by
setting the parent feature in the child.

Anthony,

There isn't actually a question in your note so I'm not sure if you are
trying to ask one...

Do you have explicit EReferences for both ends of the relationship? Have
you made the container side non-transient? And have you made both ends
proxy resolving?

There isn't actually a question in your note so I'm not sure if you are
trying to ask one...<br>
<br>
Do you have explicit EReferences for both ends of the relationship?
Have you made the container side non-transient? And have you made both
ends proxy resolving?<br>
<br>

Actually I used Teneo to save my model into DB.

Let me introduce the picture:

When the first time the model is created , the only one
ProductRegistry element is created and saved.

And then when user click the Product node in UI, I need to
show a table to list the products.

Because the products collection could be really huge, so I choose
to change them to many-to-one's (so only persist the reference from the
child to the parent) and load the one-to-many relation (parent to child)
on demand through an explicit query (make the many-reference from the
parent to the child transient). Adding to the parent is then done by
setting the parent feature in the child.

I'm not sure I completely follow what you are asking (container is set
as transient implies you don't want to serialize it), but in the XMI
serialization, to serialize a reference to the container, you need to
define a non-transient container feature (i.e., an EReference that's
the eOpposite of the containment feature).

Merks,

Yes, both ends has explicit EReferences and the container side is
transient, both ends are not proxy resolving.


The question is :

When I try to add new element which has set eContainer into resource
contents , the eContainer is removed by inverseAdd(). So I don't know
how to save these elements.

If you really need the parent and the child to be in separate resources
then you must make both ends proxy resolving, i.e., set
EReference.isResolveProxies to true. And I'm not sure how Teneo
handles it, but I imagine that a transient feature will not be
persisted, so probably you want to make the container side non-transient...

Yes, both ends has explicit EReferences and the container side is
transient, both ends are not proxy resolving.


The question is :

When I try to add new element which has set eContainer into resource
contents , the eContainer is removed by inverseAdd(). So I don't know
how to save these elements.

There isn't actually a question in your note so I'm not sure if you
are trying to ask one...

Do you have explicit EReferences for both ends of the relationship?
Have you made the container side non-transient? And have you made both
ends proxy resolving?

Actually I used Teneo to save my model into DB.

Let me introduce the picture:

When the first time the model is created , the only one
ProductRegistry element is created and saved.

And then when user click the Product node in UI, I need to
show a table to list the products.

Because the products collection could be really huge, so I
choose
to change them to many-to-one's (so only persist the reference from
the child to the parent) and load the one-to-many relation (parent to
child) on demand through an explicit query (make the many-reference
from the parent to the child transient). Adding to the parent is then
done by setting the parent feature in the child.

I'm not sure I completely follow what you are asking (container is
set as transient implies you don't want to serialize it), but in the
XMI serialization, to serialize a reference to the container, you
need to define a non-transient container feature (i.e., an
EReference that's the eOpposite of the containment feature).

contents, in inverseAdd() ,the eContainer is removed.

If I set the referenceFeature's proxyFlag as 65536 in debug mode
to make the isResolveProxy() return true, I could stop this removal.

Do I need to set something in hibernate.hbm.xml?

There isn't actually a question in your note so I'm not sure if you
are trying to ask one...&lt;br&gt;
&lt;br&gt;
Do you have explicit EReferences for both ends of the relationship?
Have you made the container side non-transient? And have you made both
ends proxy resolving?&lt;br&gt;
&lt;br&gt;

&lt;pre wrap=""&gt;Merks,

Actually I used Teneo to save my model into DB.

Let me introduce the picture:

When the first time the model is created , the only one
ProductRegistry element is created and saved.

And then when user click the Product node in UI, I need to
show a table to list the products.

Because the products collection could be really huge, so I
choose
to change them to many-to-one's (so only persist the reference from
the child to the parent) and load the one-to-many relation (parent to
child) on demand through an explicit query (make the many-reference
from the parent to the child transient). Adding to the parent is then
done by setting the parent feature in the child.

&lt;/pre&gt;
&lt;blockquote type="cite"&gt;
&lt;pre wrap=""&gt;Anthony,

I'm not sure I completely follow what you are asking (container is set
as transient implies you don't want to serialize it), but in the XMI
serialization, to serialize a reference to the container, you need to
define a non-transient container feature (i.e., an EReference that's
the eOpposite of the containment feature).

Anthony,
I am not sure but does your first remark:

If I set the referenceFeature's proxyFlag as 65536 in debug mode
to make the isResolveProxy() return true, I could stop this removal.

not already solve this issue? It seems like what Ed suggests.

Martin,

In my xxx.genmodel's properties, there is 'Contaiment Proxies'
property in 'Model' section, the description for this property
is "Whether to respect the resolveProxies setting for containment
references" and its default value is 'false'.

After I changed this value as 'true' , everything is OK.

Thanks .


Anthony

Anthony,

Sorry, I really should have thought to mention that. :-(

In my xxx.genmodel's properties, there is 'Contaiment Proxies'
property in 'Model' section, the description for this property
is "Whether to respect the resolveProxies setting for containment
references" and its default value is 'false'.

After I changed this value as 'true' , everything is OK.

Thanks .

I am not sure but does your first remark:

If I set the referenceFeature's proxyFlag as 65536 in debug mode
to make the isResolveProxy() return true, I could stop this removal.

not already solve this issue? It seems like what Ed suggests.

If you really need the parent and the child to be in separate
resources then you must make both ends proxy resolving, i.e., set
EReference.isResolveProxies to true. And I'm not sure how Teneo
handles it, but I imagine that a transient feature will not be
persisted, so probably you want to make the container side
non-transient...

Yes, both ends has explicit EReferences and the container side is
transient, both ends are not proxy resolving.


The question is :

When I try to add new element which has set eContainer into
resource
contents , the eContainer is removed by inverseAdd(). So I don't
know how to save these elements.

<pre wrap="">Anthony,

There isn't actually a question in your note so I'm not sure if you
are trying to ask one...

Do you have explicit EReferences for both ends of the relationship?
Have you made the container side non-transient? And have you made
both ends proxy resolving?

Actually I used Teneo to save my model into DB.

Let me introduce the picture:

When the first time the model is created , the only one
ProductRegistry element is created and saved.

And then when user click the Product node in UI, I need to
show a table to list the products.

Because the products collection could be really huge, so I
choose
to change them to many-to-one's (so only persist the reference
from the child to the parent) and load the one-to-many relation
(parent to child) on demand through an explicit query (make the
many-reference from the parent to the child transient). Adding to
the parent is then done by setting the parent feature in the
child.

I'm not sure I completely follow what you are asking (container
is set as transient implies you don't want to serialize it), but
in the XMI serialization, to serialize a reference to the
container, you need to define a non-transient container feature
(i.e., an EReference that's the eOpposite of the containment
feature).

So if the container is set as transient, how to persist the

Do I need to set something in hibernate.hbm.xml?

There isn't actually a question in your note so I'm not sure if you
are trying to ask one...&lt;br&gt;
&lt;br&gt;
Do you have explicit EReferences for both ends of the relationship?
Have you made the container side non-transient? And have you made
both ends proxy resolving?&lt;br&gt;

Actually I used Teneo to save my model into DB.

Let me introduce the picture:

When the first time the model is created , the only one
ProductRegistry element is created and saved.

And then when user click the Product node in UI, I need to
show a table to list the products.

Because the products collection could be really huge, so I
choose
to change them to many-to-one's (so only persist the reference from
the child to the parent) and load the one-to-many relation (parent
to child) on demand through an explicit query (make the
many-reference from the parent to the child transient). Adding to
the parent is then done by setting the parent feature in the child.

Hi,
It is not.
I have to use another resource to init the parent to get it
as EMF owner object to create AddChild command.

It seems the saving action would fail since the parent is not in the
same resource, but if the eContainer is not removed then the element is
saved in DB.

serialization, to serialize a reference to the container, you need to
define a non-transient container feature (i.e., an EReference that's the

Anthony,

There isn't actually a question in your note so I'm not sure if you are
trying to ask one...

Do you have explicit EReferences for both ends of the relationship? Have
you made the container side non-transient? And have you made both ends
proxy resolving?

Actually I used Teneo to save my model into DB.

Let me introduce the picture:

When the first time the model is created , the only one
ProductRegistry element is created and saved.

And then when user click the Product node in UI, I need to
show a table to list the products.

Because the products collection could be really huge, so I choose
to change them to many-to-one's (so only persist the reference from the
child to the parent) and load the one-to-many relation (parent to child)
on demand through an explicit query (make the many-reference from the
parent to the child transient). Adding to the parent is then done by
setting the parent feature in the child.

I'm not sure I completely follow what you are asking (container is set
as transient implies you don't want to serialize it), but in the XMI
serialization, to serialize a reference to the container, you need to
define a non-transient container feature (i.e., an EReference that's
the eOpposite of the containment feature).

Merks,

Yes, both ends has explicit EReferences and the container side is
transient, both ends are not proxy resolving.


The question is :

When I try to add new element which has set eContainer into resource
contents , the eContainer is removed by inverseAdd(). So I don't know
how to save these elements.

Anthony,

If you really need the parent and the child to be in separate resources
then you must make both ends proxy resolving, i.e., set
EReference.isResolveProxies to true. And I'm not sure how Teneo
handles it, but I imagine that a transient feature will not be
persisted, so probably you want to make the container side non-transient...

If you really need the parent and the child to be in separate resources
then you must make both ends proxy resolving, i.e., set
EReference.isResolveProxies to true. &nbsp; And I'm not sure how Teneo
handles it, but I imagine that a transient feature will not be
persisted, so probably you want to make the container side
non-transient...<br>

Yes, both ends has explicit EReferences and the container side is
transient, both ends are not proxy resolving.


The question is :

When I try to add new element which has set eContainer into resource
contents , the eContainer is removed by inverseAdd(). So I don't know
how to save these elements.

There isn't actually a question in your note so I'm not sure if you
are trying to ask one...

Do you have explicit EReferences for both ends of the relationship?
Have you made the container side non-transient? And have you made both
ends proxy resolving?

Actually I used Teneo to save my model into DB.

Let me introduce the picture:

When the first time the model is created , the only one
ProductRegistry element is created and saved.

And then when user click the Product node in UI, I need to
show a table to list the products.

Because the products collection could be really huge, so I
choose
to change them to many-to-one's (so only persist the reference from
the child to the parent) and load the one-to-many relation (parent to
child) on demand through an explicit query (make the many-reference
from the parent to the child transient). Adding to the parent is then
done by setting the parent feature in the child.

I'm not sure I completely follow what you are asking (container is
set as transient implies you don't want to serialize it), but in the
XMI serialization, to serialize a reference to the container, you
need to define a non-transient container feature (i.e., an
EReference that's the eOpposite of the containment feature).

Anthony,
I am not sure but does your first remark:

If I set the referenceFeature's proxyFlag as 65536 in debug mode
to make the isResolveProxy() return true, I could stop this removal.

not already solve this issue? It seems like what Ed suggests.

Martin,

In my xxx.genmodel's properties, there is 'Contaiment Proxies'
property in 'Model' section, the description for this property
is "Whether to respect the resolveProxies setting for containment
references" and its default value is 'false'.

After I changed this value as 'true' , everything is OK.

Thanks .


Anthony

In my xxx.genmodel's properties, there is 'Contaiment Proxies'
property in 'Model' section, the description for this property
is "Whether to respect the resolveProxies setting for containment
references" and its default value is 'false'.

After I changed this value as 'true' , everything is OK.

Thanks .

I am not sure but does your first remark:

If I set the referenceFeature's proxyFlag as 65536 in debug mode
to make the isResolveProxy() return true, I could stop this removal.

not already solve this issue? It seems like what Ed suggests.

If you really need the parent and the child to be in separate
resources then you must make both ends proxy resolving, i.e., set
EReference.isResolveProxies to true. And I'm not sure how Teneo
handles it, but I imagine that a transient feature will not be
persisted, so probably you want to make the container side
non-transient...

<pre wrap="">Merks,

Yes, both ends has explicit EReferences and the container side is
transient, both ends are not proxy resolving.


The question is :

When I try to add new element which has set eContainer into
resource
contents , the eContainer is removed by inverseAdd(). So I don't
know how to save these elements.

<pre wrap="">Anthony,

There isn't actually a question in your note so I'm not sure if you
are trying to ask one...

Do you have explicit EReferences for both ends of the relationship?
Have you made the container side non-transient? And have you made
both ends proxy resolving?

Actually I used Teneo to save my model into DB.

Let me introduce the picture:

When the first time the model is created , the only one
ProductRegistry element is created and saved.

And then when user click the Product node in UI, I need to
show a table to list the products.

Because the products collection could be really huge, so I
choose
to change them to many-to-one's (so only persist the reference
from the child to the parent) and load the one-to-many relation
(parent to child) on demand through an explicit query (make the
many-reference from the parent to the child transient). Adding to
the parent is then done by setting the parent feature in the
child.

I'm not sure I completely follow what you are asking (container
is set as transient implies you don't want to serialize it), but
in the XMI serialization, to serialize a reference to the
container, you need to define a non-transient container feature
(i.e., an EReference that's the eOpposite of the containment
feature).

Merks,

Thanks.

&amp;lt;pre wrap=""&amp;gt;Anthony,

&amp;lt;/pre&amp;gt;
&amp;lt;/blockquote&amp;gt;

&amp;lt;/pre&amp;gt;
&amp;lt;blockquote type="cite"
