Hi Raymond,

I have come across those as well some time ago, and it turned out that I didn't strictly obey all the EOF commandments back then.

http://wiki.wocommunity.org/display/documentation/EOF-Using+EOF-The+EOF+Commandments

If you don't follow those, EOF will fight back with all sorts of strange effects, like those NullPointerExceptions, or missing snapshot exceptions and the like. So I suggest you doublecheck those thoroughly.

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.
