Python Dynamic popuMenu - menuItem crash

Hi all,

Has anyone experience a crash coming from a dynaic popuMenu(menuItem) with Python inMaya?

I have a UI and dynamically populating the window based on my selection and on each button that created I also assign a popupMenu to access menuItems if you hit the right click mouse button.

The UI works great but when I click the menuItem Maya crash. and it happened kind of randomly. Sometimes I can clik once or twice but crash after sometimes it crash right away.

I apologixe I am not allowed to post the code here. Just wondering if anyone experienced it and is there any tricks around it. Thanks

well without code this is groping in the dark.

The most prevelant cause of UI-related crashes are probably due to a control attempting to delete itself (or a parent of itself):

# this button crashes maya
cmds.button('MyButton', label='Click & Crash', command='deleteUI MyButton')

# this doesn't
cmds.button('MyButton', label='Click Safe', command='cmds.evalDeferred("deleteUI MyButton")')

Hi Nyro,

I am sorry i am unable to post the code. But based on your suggestion I troubleshoot my script and get it to run properly, basically in the command I tried to run the same script to refresh my UI. Seems like the popupMenu got an infinite loop so I stop that and it worked.

Thanks a lot
