Iphone Core Data Internal Inconsistency?

Class MailMessage could be implemented in a library or somewhere else in the framework. As Objective C does not implement namespaces, one of the two will be used. Which one is undefined.

Try giving your class a different name to quickly resolve the issue.

I never would've thought about that..... fixed everything right up... :) Thanks a million! :D Though I have to admit, the new xCode 4 was really annoying when it came to changing the name... I had to create a new entity and copy all the attributes/connections... /: – Suicidal Jun 29 at 3:00.

Look for a message like this from the debugger. It will confirm what Benjamin says. Class MailMesssage is implemented in both /Developer/Platforms/iPhoneSimulator.

Platform/Developer/SDKs/iPhoneSimulator4.2. Sdk/System/Library/PrivateFrameworks/Message. Framework/Message and /Users/home/Library/Application Support/iPhone Simulator/4.2/Applications/FFFFFFFF-FFFF-0000-0000-AAAAAAAAAAA/Projects. App/Projects.

One of the two will be used. Which one is undefined.

Haven't tried it my self, but if it does, it deserves a thumbs up... :) – Suicidal Jun 29 at 4:37.

Try resetting the Simulator or uninstalling the application from your device. Often the NSInternalInconsistencyException has to do with problems with changing the datamodel and the database not being updated accordingly.

I've tried that :( still same error. – kiyoshi Aug 18 '09 at 1:23.

I was able to workaround this by creating the MailMessage object before presenting the modal view controller. Once the MailMessage object was already created, saving changes did not present a problem. A strange workaround and not addressing the actual problem as far as I know, but it works.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
