Description:
When I try to change the Foreign key name in the 'Alter Table' Form in 'Foreign Keys' Tab the exception occurred. Exception will occur after I specify a FK name and trying to edit the FK name example: from fk_test -> fk_test2. More detailin how to repeat.

How to repeat:
1. Create a new schema and 2 tables
2. Alter table #2 to add a foreign key
3. Go into Foreign Keys tab
4. Give some name ex: fk_test
5. Choose the referenced table
6. return to FK name and press F2
7. Type any character and exception occurred

I'm using Windows 7 32-bit with .NET Framework 3.5 SP 1 installed. Here I included the error stack trace.

Exception = System.NullReferenceException
Message = Object reference not set to an instance of an object.
FullText = System.NullReferenceException: Object reference not set to an instance of an object.
