Hi List,
I have a big problem to save my data. When I set the relastionship entity1.setEntity2Relationship(entity2), I get a java NullPointerException at the method who set the relation :
addObjectToBothSidesOfRelationshipWithKey(entity2, _Enity1.ENTITY2_KEY); <-----
When I try another way entity1.setEntity2(enity2) I get the same java NullPointerException when I want to save entity1.
