Hi,
I'm having troubles persisting embeddable classes, when calling
pm.makePersist(object); I get the following ClassCastException
java.lang.ClassCastException: com.myprojecyt.MyEmbeddableClass
at org.datanucleus.state.JDOStateManagerImpl.initialiseForEmbedded
(JDOStateManagerImpl.java:357)
at org.datanucleus.state.StateManagerFactory.newStateManagerForEmbedded

(DatastoreFieldManager.java:769)
at org.datanucleus.state.AbstractStateManager.providedObjectField
(AbstractStateManager.java:1037)
The class that I'm trying to persist looks roughly like this
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Entity {
@Persistent
@Embedded
private MyEmbeddableClass myEmbeddableClass;
......
}
And in an extra file I declare the class that has to be embedded
@PersistenceCapable
@EmbeddedOnly
public class MyEmbeddableClass{
@Persistent
private String text;
...
}
Anybody has some experience with embeddable classes?
Thanks in advance
Dominik
