I probably didn't respond to this thread when I posted earlier, but
this problem ended up being inheritance-across-models-that-eof-thinks-
are-in-different-databases thing I ranted about a couple days ago
(described in http://en.wikibooks.org/wiki/Programming:WebObjects/EOF/
Using_EOF/Common_Pitfalls_and_Troubleshooting ). I did, however, log
a radar bug for that.
Actually, interestingly, from tracing through finding my problem, I
believe what you're seeing is exactly the same bug in a different
form. It's the same little block of code that turns off PK
generation, just triggered from two different scenarios.

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.
