Created attachment 114256 [details] stacktrace
I am sorry, I am not able to reproduce this issue and the attached stacktrace is not sufficient to track the problem down. Are you still able to reproduce this problem? If so, could you, please, provide more details? It would be ideal to attach the problematic form (both .java and .form files) saved in the last good state and describe _exact_ steps that lead to the exception. Thank you in advance.
