Hi Dave, I started it all over. The files out of sync problem was so bad that my very simple application was screwed to the point it was not usable anymore. So I trashed it. It seems that Eclipse really doesn’t like when we make lots of changes to the eomodel. For instance, Eclipse will simply and very often trash one the specific entity.plist files that I was trying to change.
I am working on a new approach and if I face any of the reported problems I will email the list with the project files.
