What is the exact URI you want to save to (does it end in ".organisation")?
Is this executed against the latest CVS sources?
There is a recent change in how eResource() works for CDOPersistable
objects.
With your info below I recognize that there might be issues with
re-attached objects.
Currently an object always returns the CDOResource it was initially
attached to.
Please open a Bugzilla for this.
The latest CVS sources contain a number of bug fixes (we have
integration tests now).
Please try if the problem persists with that version.
Did you try to copy the objects from a CDOResource to the XMIResource?
There are newsgroup threads discussing that.
If all does not help, could you send me a zip with the projects so that
I can play around with them?
Cheers

I think I know what happened to your exported objects. CDO generally
loads objects on demand (even contained ones). Only the root objects are
loaded together with the resource. That's why your root object is
properly serialized to XMI. The contained objects (roles, users,
processes) had not been loaded when you attached the root object to a
different resource. The proxy URIs still apply to the CDO resource but
that is no longer the container of the root. So they're not loaded
anymore and don't get resolved.
I really suggest that you EcoreUtil.copy() the CDO resource and attach
the copy to the XMI resource.

I've opened Bugzilla

The main outcome is that you have to use something like
protected void preLoadResource(CDOResource cdoResource)
{
for (Iterator it = EcoreUtil.getAllContents(cdoResource, true);
it.hasNext();)
{
CDOPersistable persistable = (CDOPersistable) it.next();
persistable.cdoLoad();
}
}
before you try to copy the resource with EcoreUtil.
I have to admit that I'm not completely sure about the influence of
resolveProxies during the copy process.
It seems that it does not automatically lead to loading CDOPersistables
that are proxies.
Ed: Could you explain a bit?
Maybe CDO could override an EObject method so that resolving a proxy
would also load it.
At the moment cdoLoad is only called on explicit access to persistent
features.

In this case it is only one resource.
CDO uses proxy URIs for contained objects, too.
I assume that resolving such proxies doesn't do anything, because the
resource is already loaded from a ResourceSet perspective.

If you want you can open an enhancement request asking for optimized
"Preloading Support".

Eike,
Whenever a proxy is resolved, if the result is different from the
original object, it will replace the original, as in this EcoreEList method:
protected EObject resolve(int index, EObject eObject)
{
EObject resolved = resolveProxy(eObject);
if (resolved != eObject)
{
Object oldObject = data[index];
assign(index, validate(index, resolved));
didSet(index, resolved, oldObject);
So the code doesn't care whether it's in the same resource or not...

We should use getAllProperContents instead of getAllContents
Now I am implementing the load and save action into the CDOExplorer.
Can I add this to repository, and how can I do this?

My proposal for a preLoadResource loads all objects contained in that resource.
I verified this with a test case.
If your resource does not get fully loaded, please explain a bit more.

This seems a bit of a brute force ;-)
The effort can be O(n*n) where n is the number of objects in the resource.

I already understood that your method works like that ;-)
But I asked you to explain, what exactly did not work with my method.
As I said, it works for me (and performs better than yours).
Can you provide a zip with the source code that you used to test my method?

I could reproduce your issue in /org.eclipse.emf.cdo.tests/src/org/eclipse/emf/cdo/tests/mod el1/SerializationTest.java
Look for testExportThreeLevels().
The issue is caused because EObject.eContents() does not call cdoLoad().
I've fixed this in CDOPersistentImpl:
/**
* @ADDED
*/
@Override
public EList eContents()
{
cdoLoad();
return super.eContents();
}
The changes are committed to CVS.
Can you please verify that it works for you?
Cheers

I'd appreciate if you could verify that the new features satisfy your needs.
There is a remaining issue with CDOEditors that still have resources already

Resource deletion occurs in a transaction. Currently it can leave orphaned

in the scope of another Bugzilla.

Chris,
What is the exact URI you want to save to (does it end in ".organisation")?
Is this executed against the latest CVS sources?
There is a recent change in how eResource() works for CDOPersistable
objects.
With your info below I recognize that there might be issues with
re-attached objects.
Currently an object always returns the CDOResource it was initially
attached to.
Please open a Bugzilla for this.
The latest CVS sources contain a number of bug fixes (we have
integration tests now).
Please try if the problem persists with that version.
Did you try to copy the objects from a CDOResource to the XMIResource?
There are newsgroup threads discussing that.
If all does not help, could you send me a zip with the projects so that
I can play around with them?
Cheers
/Eike

Chris,
I think I know what happened to your exported objects. CDO generally
loads objects on demand (even contained ones). Only the root objects are
loaded together with the resource. That's why your root object is
properly serialized to XMI. The contained objects (roles, users,
processes) had not been loaded when you attached the root object to a
different resource. The proxy URIs still apply to the CDO resource but
that is no longer the container of the root. So they're not loaded
anymore and don't get resolved.
I really suggest that you EcoreUtil.copy() the CDO resource and attach
the copy to the XMI resource.
Cheers

Chris,
I've opened Bugzilla
https://bugs.eclipse.org/bugs/show_bug.cgi?id=154522 for it.
The main outcome is that you have to use something like
protected void preLoadResource(CDOResource cdoResource)
{
for (Iterator it = EcoreUtil.getAllContents(cdoResource, true);
it.hasNext();)
{
CDOPersistable persistable = (CDOPersistable) it.next();
persistable.cdoLoad();
}
}
before you try to copy the resource with EcoreUtil.
I have to admit that I'm not completely sure about the influence of
resolveProxies during the copy process.
It seems that it does not automatically lead to loading CDOPersistables
that are proxies.
Ed: Could you explain a bit?
Maybe CDO could override an EObject method so that resolving a proxy
would also load it.
At the moment cdoLoad is only called on explicit access to persistent
features.
Cheers

Eike,
By default, EcoreUtil.Copier should resolve proxies as it copies and
that should cause referenced resources to be loaded as necessary.

In this case it is only one resource.
CDO uses proxy URIs for contained objects, too.
I assume that resolving such proxies doesn't do anything, because the
resource is already loaded from a ResourceSet perspective.

Chris,
The solution I outlined below will work, but is unefficient for large
resources.
It loads the resource object by object, each causing a signal to and
from the server.
If you want you can open an enhancement request asking for optimized
"Preloading Support".
Cheers

Eike,
Whenever a proxy is resolved, if the result is different from the
original object, it will replace the original, as in this EcoreEList method:
protected EObject resolve(int index, EObject eObject)
{
EObject resolved = resolveProxy(eObject);
if (resolved != eObject)
{
Object oldObject = data[index];
assign(index, validate(index, resolved));
didSet(index, resolved, oldObject);
So the code doesn't care whether it's in the same resource or not...

We should use getAllProperContents instead of getAllContents
Now I am implementing the load and save action into the CDOExplorer.
Can I add this to repository, and how can I do this?

My proposal for a preLoadResource loads all objects contained in that resource.
I verified this with a test case.
If your resource does not get fully loaded, please explain a bit more.

This seems a bit of a brute force ;-)
The effort can be O(n*n) where n is the number of objects in the resource.

I already understood that your method works like that ;-)
But I asked you to explain, what exactly did not work with my method.
As I said, it works for me (and performs better than yours).
Can you provide a zip with the source code that you used to test my method?

Chris,
Please don't spend any more effort for constructing an example!
I could reproduce your issue in /org.eclipse.emf.cdo.tests/src/org/eclipse/emf/cdo/tests/mod el1/SerializationTest.java
Look for testExportThreeLevels().
The issue is caused because EObject.eContents() does not call cdoLoad().
I've fixed this in CDOPersistentImpl:
/**
* @ADDED
*/
@Override
public EList eContents()
{
cdoLoad();
return super.eContents();
}
The changes are committed to CVS.
Can you please verify that it works for you?
Cheers

Import Export Button patch:
Would it be possible to implement the delete function for the cdo
resources? Can I do it myself, where have I to look for??
Thanx Chris

Chris,
The CVS HEAD version addresses both enhancements, import/export and delete.
You can alternatively download zips from
http://emft.eclipse.org/technology/emft/downloads/downloads- viewer.php?proj=cdo&s=1.0.0/N200609061442/
I'd appreciate if you could verify that the new features satisfy your needs.
There is a remaining issue with CDOEditors that still have resources already
deleted by other sessions, but I will fix that in another Bugzilla.
Btw. resource deletions have been rather complicated to implement because
objects in other resources can be affected by this operation. The current
approach automatically removes such references and finally transmits
invalidation notifications for changed objects.
Resource deletion occurs in a transaction. Currently it can leave orphaned
objects in the database. I will implement a persistent garbage collection
in the scope of another Bugzilla.
Cheers
/Eike
