I am sorry, I am not able to reproduce this issue. Are you still able to reproduce it? If so, could you, please, 
provide more details (exact steps to reproduce would be ideal)? It is clear (from the stack trace) what is null, but it 
is not clear how this can happen and hence, what should be done in this case. Thank you in advance.

No additional information provided => closing as non-reproducible.

I just run into this bug and can reproduce it always. I uploaded a new stacktrace and provided some user info...

> started editing a jpanel with invalid components (the jpanel must really be edited because of some refactoring)

Sorry but I can't still reproduce it. Made a form with a custom component and removed its JAR. The form opened with 
an "Invalid component". I chose to edit the form anyway - the invalid component was removed. That's how it should 
behave. No exception. Tried both in 6.1 and current 6.5 dev.

Can you reproduce this only with the one form, or in general with any form containing an invalid component (missing 
class)? If specific to one form, can you attach here?

No additional information provided => closing as non-reproducible. Feel free to reopen it if you are still able to 
reproduce it, but provide _exact_ steps to reproduce then. Thank you in advance.
