Major Description
After editing a new process for quite some time, the editor stops allowing input on an Assign (cannot change name). I then see errors in a If condition - I had followed the suggestion of the code completion and created a condition expression with null:numberOfTickets. It would not let me edit the field. I next opened the bpel file in a text editor and removed the offending if condition, but upon opening the editor would still not let me edit this field (or any other).
I will attach the project files.
