Same named element in 2 different xsd [message #82580]

Hi Martin,

I have the same named element "ParentTree" in 2 different xsds eg
navigation.xsd and topology.xsd. Navigation.xsd reference topology.xsd. So
when I try a datastore.initialize, teneo finds the same eClass in
"ParentTree" in navigation and topology. Is there a way around this? Can I
redirect one of the ParentTree to point to a different table in the
database without explicitly changing the xsd?

Hi Julia,
If the problem is that both eclasses are stored in the same table then you can use an
@Table(name="myname") annotation on the eclass to control were it is stored. You can set this
annotation in the xsd, the ecore or in a separate xml file.

See here for some extra info:

Hi Martin,

Actually, it's the same named element and structure in both xsds but will
hold different data. Would I not need 2 different tables in the datastore?
Would changing the table="ParentTree" to table="ParentTree_nav" in
package.jdo for one of the xsds work? It's probably a hack :-). Would
following the links you provided work in this case?

Hi Julia,
I would assume that they are conceptually different (as they are modelled each as their own type).
So in this case they would need different tables.

To solve the duplicate eclass name issue (when generating the jdo file) the best is to set the
following property
PersistenceOptions.QUALIFY_ENTITY_NAME
to
PersistenceOptions.QUALIFY_ENTITY_NAME_NSPREFIX);

This property must be set to generate the jdo file. However passing properties can not be done for
the right-click menu-generate-jdo option. You have to generate the jdo file programmatically. This
is not difficult, just make a class with a static main method in your model project and call the
following method:
JpoxHelper.INSTANCE.generateMapping(your_epackages, options)

this will return the jdo file.

Hi Martin,

May be at some stage teneo can implement some extension point so that
one can set these options in Window -> Preferences... for teneo.
