Hi everyone.

i've been building an app since 1 month using NSFetchedResultsController and i was testing the app on the 3.1.2 SDK. The poblem is that i've been using NSFetchedResultsController everywhere in my app and was working on the 3.1.2 version of the SDK, now my client say that i should make it compatible with the 3.0 version and the deadline is almost there.

But is crashing everytime i change an object handled by the contoller, the application is crashing with very weird errors.

The problem occure when removing the last object in a section and when a change make an object love to another section.

I've been using a sample code from "More iPhone 3 Development Tackling iPhone SDK 3" by Dave Mark and Jeff LaMarche. I've also included some changes from link text

Here is a sample output of the console when the application is crashing.

* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of sections. The number of sections contained in the table view after the update (1) must be equal to the number of sections contained in the table view before the update (2), plus or minus the number of sections inserted or deleted (2 inserted, 0 deleted).' 2010-03-14 16:23:29.758 Instaproofs[5879:207] Stack: ( 807902715, 7364425, 807986683, 811271572, 815059090, 815007323, 211023, 4363331, 810589786, 807635429, 810579728, 3620573, 3620227, 3614682, 3609719, 27337, 810595174, 807686849, 807683624, 839142449, 839142646, 814752238 )

If i knew that NSFetchedResultsController is so buggy, i would never used it.

So basicaly i need the my NSFetchedResultsControllerDelegate to work fine on the 3.0 and above SDKs.

It would be life saver if someone help me figure out what i'm doing wrong.
