Hey 
I have an a RelationshipEntity that I want to persist, however I get a NullPointerExcpetion in the OGM . The special thing about the Entity is that it is a Generic meaning RelName extends Persistable {}. When the construct to persist is a List of these objects it works, however when I have a simple field of this relationship I get the following error:
java.lang.NullPointerException

Are Generic Entities somehow supported, am I missing something or is this a known problem that a workaround exists for? I thought maybe one could write a custom converter?
