It has recently come up on the list again about a known issue when
using Core Data + G.C. + SQL NSPersistantDocumentStore. I have a
document based application that I am about to release where I have
been using this exact combination through it's entire development. I
have noticed this issue with the "hang while saving", but at the time
I had thought that it was caused by me corrupting the document's
object graph. Indeed the problem seemed to stop once I had fixed some
of my App's logic and I haven't seen the issue since.
I think you're getting lucky. I can certainly still repro this bug.
And my Radar has not come back 'fixed'.
I find it quite bothersome that a bug that causes user data loss is
still unfixed in 10.5.6. It must be a hard nut to crack.

If it's not too much trouble are you able to send me your repro project?
I'm wondering why it's not happening with my project anymore.
To email@hidden:
I am dirtying the document before each save and it still isn't
happening. In certain instances, the MOC's undoManager is cleared
before saving, but other times it's not (I'm not sure if this matters
for this instance...).
I am also running 10.5.6 + Xcode 3.1.2.
Thank you all for your comments!
