Hi,
My app was working fine and I made few changes. Suddenly, it
cannot create new entities any more. It can modify the existing
entities. I reverted my changes back to where it was. Problem doesn't
go away. This is in the local environment. I deleted the data file.
New data file is created with other entities. But this problem still
exists for the affected entity type. I attached the exception.
Exception doesn't tell anything. Now I am stuck. Please help find out
the root cause of this problem.
Thanks,
Prasad
