I can reproduce this issue, but don’t know why.
I upload a new log file. you can see:
16:42. I open VP
I create a class, and create new attribute through shortcut. it works.
I just create 3 attributes, move the class.
then I leave and work on other app.
17:36: I return to VP, and found the shortcut doesn’t work. you can see the NullPointerException
BTW. this happened in my old MBP. and also happened in my new MBP.
