Description

You modify an object and then call -[EOEditingContext saveChanges] but nothing gets saved to the database.

Diagnostics

Set a breakpoint on -[EOEditingContext saveChanges] and do a MulleEOStructureDump on the EOEditingContext. Check if your edits appear there.

The Edits do not show up

• The object resides in a different EOEditingContext
• The object did not call willChange before the change
• You are using old code but set MulleEOGenericRecordNoBuggyKVCAccessors to YES and use EOGenericRecords broken KVC

The Edits show up

• The EOEditingContext is nested in another EOEditingContext
