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 this exception. Thank you in advance.
Comment 3 David Konecny 2011-08-04 21:26:38 UTC 
I tried and I can reproduce it. But it does look like a corner case so perhaps P4. Try this (eg. in 7.0.1):

* open web.project/src/org/netbeans/modules/web/project/ui/customizer/CustomizerJavadoc.java

* change layout to Freeform

* select two aligned JTextFields at the bottom (Browser Window Title and Encoding)

* drag them and drop them in between two checkboxes (for example in between @author and @version)

That always result in Assert for me.

Thank you for the additional information. I am able to reproduce the exception now. I am attaching a test-case based on the form that you mentioned.

Steps to reproduce:
1. Open the attached form.
2. Select two buttons at the bottom.
3. Move them such that the left top corner of jButton1 is aligned
   with the left top corner of JToggleButton2 => the exception is thrown.
Comment 7 Tomas Pavek 2011-10-12 13:37:15 UTC 
The test case is to move multiple components from a different layout to "free design". It works with just one component.
