I’m using the V2 scripts and it looks like vtkCPProcessor::RequestDataDescription() is always returning non-zero values for the new GUI generated scripts. Things still work correctly with the legacy Catalyst scripts. My PV version may be a week old or so though so apologies if this issue is fixed already.
That doesn’t seem to fix the issue. I just updated to PV master and am still experiencing the same issue. I have a print statement after I call vtkCPProcessor::RequestDataDescription() so I can see that it’s still getting where it shouldn’t. The data extracts aren’t getting created but I’m still generating the grid unnecessarily.
report and bug with details and I’ll take a look. I know there are cases where the script cannot determine decisively if any grid will be needed and will just assume as such – can’t remember off the top of my head. Report details and I’ll see what’s going on and what’s expected.
I am confused…are you saying it doesn’t work in master or doesnt’ work despite my changes? I cannot reproduce the issue with changes in https://gitlab.kitware.com/paraview/paraview/-/merge_requests/4594.
