Hello, I'm trying to write a plugin based on a programmable filter in order to extract a single block from a multiblockdataset (with a single level tree) in input chosing it through a slider in the property panel. I need help to automatically set the range of the slider (the higher limit as the lower is always 0) as the number of blocks of the multiblockdataset in input, but the XML ServerManager definition of the slider is not clear enough for me.
I'm trying to follow Utkarsh suggestion in https://public.kitware.com/pipermail/paraview/2009-March/011599.html but I'm missing how to recovery the number of blocks of the input of the programmable filter and how to set it as the upper value of the slider range. Thank you in advance for your kind help Alessandro
