Hi all,
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.
Me question now is, is it known if there are any particular types of
models that can cause this hang? I am using SQL since I will be
storing one picture and multiple images of floor plans per document as
per the Core Data BLOBs docs. My data model is has about 12 entities,
but will only have a few instances of each object. I haven't seen
this issue in quite a while and I was wondering if it might be safe to
release it with SQL set as the default backing store?
Thank you for any insights you may have into this matter.
