Hi Cory,
Trying to find out what causes the former problems, I inserted a line that just
sets the property that got collected so far:
https://github.com/romangrothausmann/ParaView_scripts/commit/b8058f774535398da3767048219df12d6354e6c5#diff-2804420278bfff084788b82c715c452eR59
It already aborts on the first property encountered (ForceUseCache):
<paraview.servermanager.GeometryRepresentation object at 0x7f7b591fc250>
ForceUseCache 0
Traceback (most recent call last):
File "/net/home/paraview/scripts/pvsm-multi.py", line 91, in <module>
main()
File "/net/home/paraview/scripts/pvsm-multi.py", line 59, in main
pvs.SetProperties(repr, **d)
File
"/opt/paraview-5.3.0_GL1/lib/paraview-5.3/site-packages/paraview/simple.py",
line 567, in SetProperties
raise AttributeError("object has no property %s" % param)
AttributeError: object has no property ForceUseCache
Is ListProperties() returning properties that are not part of the specific
object that is calling ListProperties()?
Many thanks for any help or hints,
Roman
