I'm running into a strange problem and am looking for hints on what
might be the cause. I'm using NSPersistentDocument with an SQL store.
Saving works fine, but if I choose Save As... then data is lost in
the saving process. The data that is lost seems to be specific to
only one type of entity. And it only seems to be attribute values
(all of them) that are lost. The relationships for the entity DO seem
to be saved correctly.
The last bit of trivia is that if I make a change to one of the
attribute values that get lost before choosing "save as" then the
attributes for that particular entity are saved correctly. So objects
that have changes always save as correctly. But if objects don't have
changes, then for one entity type (out of many) attribute values are
lost.
Any ideas on what might be wrong, or how to debug this?
Thanks,
Jesse
