Exception on selecting Insert/Delete Constraint for table create UI

To reproduce:

1. Create a new table in PostgreSQL 9.1 or MySQL with 3 columns a,b,c

2. Go to the Constraints tab and create 1 constraint

3. Then right click near the rows as in the attached screenshot and insert and delete a few Constraints and you get the below exception.

I can help you reproduce if you are not able to
