My Platform is Windows 7 x64 with JDeveloper 22.214.171.124
JDeveloper shows an error when I do this:
1) Create a new Database Diagram.
2) Create a Table in this Database Diagram.
3) Delete the Database Diagram.
4) Try to create a new Database Diagram again.
5) JDeveloper shows a Fatal Error, and the ADF Model Project still to be corrupt after restart JDeveloper.
The same happens with UML diagrams.
Do you know any solution for that?
