I'm getting the following error using DataNucleus with Google App
Engine:
org.datanucleus.metadata.InvalidMetaDataException: Field "test" in
class "Wrapper" has been defined as a Collection but the element type
has not been specified!
It seems DataNucleus doesn't figure out the collection type when the
type is specified in the declaration of a class.
For example, the following fails with an InvalidMetaDataException as
noted above...
public class Wrapper {
...
@Persistent
private Test test;
...
}
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Test extends ArrayList<String> {
...
}
Is there a way to change my annotations so that DataNucleus will
accept my type declaration, or do I have to change my code?
I posted this to the DataNucleus forum on Aug. 13 but haven't heard a
peep.
Thanks for any help,
Peter
