I have a unstructured vtk mesh with certain “group” labels as strings for the cells. When I try to color the plot by these labels using the “Interpret values as categories”, the legend shows the correct categories in the model, but the whole model has the “NaN”-color.
If I am not hallucinating, this used to work in earlier versions (pre 5.10). I also cannot extract these cells based on the group property:
File "C:\Program Files\ParaView 5.11.0\bin\Lib\site-packages\paraview\detail\python_selector.py", line 90, in execute
RuntimeError: Expression '(Group == "Brick1")' did not produce a valid mask array. The value produced is of the type '<class 'bool'>'. This typically implies a malformed expression. Verify that the expression is valid
Here is an attached simplified vtk file with this problem:

Hi @wtfermi !
The selection editor have changed a lot between 5.10 and 5.11. So there is perhaps a regression here.
Maybe @spyridon97 would have time to look at it?
Otherwise, you can open an issue at: https://gitlab.kitware.com/paraview/paraview/-/issues
@Francois_Mazen why do you think that the selection editor is relevant to this?
@cory.quammen would you like me to look into this?
The second part of the message with the extract selection triggers a crash in
vtkSelection, so it reminded me your expertise with the selection editor (sorry if I am wrong):

I see, i need to explore it then.
The second issue can not be resolved, because a vtkStringArray can not be mapped to a numpy array which is used by the python selector which is used by the Find Data Panel. But i will make it not crash.
The first issue seems to have been introduced on 5.11. I checked 5.10 and 5.9 and it was working just fine. I will explore what happened.
