Interesting...I also had faulting issues with 1.2B1. (past tense because
I needed a fix very fast; so I downgraded back to M5, which is what I
was using before). The error I was getting wasn't a "toMany"
relationship, though. But, the behavior there was also a bit
stochastic... sometimes it worked, and sometimes it didn't; in May,
things will be in more of a position for myself (and also for the
company using the software) to where I can dig deeper into this. In the
meanwhile, this is the exception I was getting:
org.objectstyle.cayenne.FaultFailureException

I double checked, and there all of the relationships are correct in the
db (and, despite what the exception says, there is a row in
AssignmentParameters with the assignmentid FK of 1590).
Line 49 of Assignment.java looks like:
if
(this.getParameters().getPermitInvalidTransactions().booleanValue()) {
Line 68 of _AssignmentParameters.java looks like:
return (Boolean)readProperty("permitInvalidTransactions");
I'll look into this deeper, like I said, probably at the beginning of
May... I didn't mention it before since I haven't had time to check if
it was a a "me" issue or a "cayenne" issue. But th fact that other
people seem to be having some trouble with fault resolving suggests that
it's not a "me issue", so I thought I'd add what little information I
have atm.
