This is a completely useless issue report, since it gives no information about the situation in which the problem occurred. Since it is almost certainly a problem with the user's mapping file, this issue should be redirected to the user forum.

The line in the sourcecode is:
model.getKey().createForeignKeyOfClass( model.getOwner().getPersistentClass() );
		
Tinkering with the sourcecode showed that the problem is that model.getKey() returned null.
