I am sorry, I am not able to reproduce this issue and the attached stack-trace
is not sufficient to track the problem down. Are you still able to reproduce
it? 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.

Project that exhibits the error.

1) Open up attached project. 
2) Open NewJFrame.java in designer.
3) Try to move textField4 to the left a bit.

This AssertionError is thrown.

Thank you for a reproducible test-case. I was able to reproduce the exception using the attached project and the described steps.
Comment 5 Tomas Pavek 2011-10-26 19:42:08 UTC 
I can reproduce this in build 201110120600, but not in current build. Must have been fixed recently together with something else.
