Any ideas why I may have got this error:
Error: java.lang.IllegalStateException
Reason: Encountered a newly inserted EO with an owns desstination
relationship but no snapshot.
A clue is that problem involved a relationship with the "Owns
Destination" property set. These aren't common in many eomodels, so
this should help narrow down the possibilities. An "Owns Destination"
property means that the destination object can't exist without being in
a relationship. So if such an object is removed from a relationship
but not placed in another relationship by the time its editing context
is sent a saveChanges() message, the destination object will be deleted
from the DB automatically.
It's not clear to me from the error message whether the source or
destination object has no snapshot. But a newly-inserted object won't
have a snapshot until it has been saved to the DB, so I'm guessing that
the destination object has no snapshot.
Because you know what operations occurred prior to this exception, you
should be able to make some educated guesses about why it occurred and
test these guesses by changing the operations.
