Sorry for the delay I was very busy this week.
Which inheritance strategy are you using ? Are you using the a discriminator
or a different node type per Class ?
There are 2 possibilities :
1/ Using a different node type per class in the hierarchy, here is a example
from the unit test. The implement-descriptor is not mandatory.
<class-descriptor
className="org.apache.jackrabbit.ocm.testmodel.inheritance.impl.FolderImpl"
jcrType="ocm:folderimpl"
extend="org.apache.jackrabbit.ocm.testmodel.inheritance.impl.CmsObjectImpl"
discriminator="false" >
<implement-descriptor
interfaceName="org.apache.jackrabbit.ocm.testmodel.interfaces.Folder"
/>
<collection-descriptor fieldName="children" proxy="true" autoUpdate="false"
elementClassName="org.apache.jackrabbit.ocm.testmodel.inheritance.impl.CmsObjectImpl"
collectionConverter="org.apache.jackrabbit.ocm.manager.collectionconverter.impl.NTCollectionConverterImpl"
/>
</class-descriptor >
2/ Using a discriminator (discriminator =true). It can be used when you are
using the same node type for the complete class hierarchy. There is no unit
tests on collection-descriptor with a discriminator. So, I will write a new
unit test for this use cases and I will give some feedback. So maybe there
are some bug for this kind of situation.
Again sorry for the delay.
