Summary: ChimeraX bug report submissionkvfinder: self._positions is None

Resolution: can't reproduce
Status: acceptedclosed

I cannot reproduce this on our Windows 11 machine. It's also a mystery to me why there are 3 consecutive identical kvfinder commands in the log. I think I've seen that in a few other tickets. And only the third immediately gives the error.

comment:3 by Tom Goddard, 3 months ago

The Model._positions is None problem is a result of asking whether a closed model is displayed. When a Model is closed its self._positions is set to None. So some how the kvfinder color_func() routine is getting hold of a structure s that has been closed.

File "C:\Program Files\ChimeraX 1.10\bin\Lib\site-
packages\chimerax\kvfinder\tool.py", line 201, in color_func  
if s.display and s.atoms.displays.any():  
^^^^^^^^^  
File "C:\Program Files\ChimeraX 1.10\bin\Lib\site-
packages\chimerax\atomic\structure.py", line 529, in _get_display  
return Model.display.fget(self)  
^^^^^^^^^^^^^^^^^^^^^^^^  
File "C:\Program Files\ChimeraX 1.10\bin\Lib\site-
packages\chimerax\graphics\drawing.py", line 389, in get_display  
return self._any_displayed_positions and len(self._positions) > 0  
^^^^^^^^^^^^^^^^^^^^  
TypeError: object of type 'NoneType' has no len()
