abstract (though the same problem occurs either way). When I run my app, and create new Entity B's, the insert statements don't include the primary key (resulting in an integrity constraint violation). If i edit the model and simply remove the parent entity reference from Entity B, and restart, everything works perfectly. That fix is ACTUALLY is not that big of a deal from a runtime perspective, except that I need the parent reference for EOGenerator to work properly (basically I care more about the inherited methods than I particularly care about it actually having a relationship in the model). Anyone seen this one before? It's been driving me crazy today -- I have to believe I'm just overlooking something silly.

Are there any entities with a relationship to the parent that have the relationship marked as Propogate Primary Key? If have seen this cause the primary key to not get generated even the objects in question were created but not related. I have been bitten by that recently, and it was very hard to track down.


I can confirm that problem: I've got exactly the same bug having primary key propagation set in parent entity relationship. This bug is very hard to track indeed: did you already report it to radar? If not, I can fill a report.
