Both my cousin and I are having the same issue on two different computers, two different different project, and two different versions of oracle database as the backend.
When we try to add the new Domain Model we get the following error after it says "Reading database schema..." for a while:
Connection error, ExceptionSystem.NullReferenceException, Details:Object reference not set to an instance of an object.
Maybe related to the other error I'm getting?
Please help, thanks.
