Probing of groups of groups
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
I have noticed that some filters does not support "groups of groups" as its input. Thanks Berg, it has been fixed for Glyph filter (http://public.kitware.com/pipermail/paraview/2006-November/004080.html) It would be nice, if similar patch could be done for the Probe filter too.
Unfortunately, such state is not even detected and reported in some comprehensible way. It would also be nice if a module, not supporting groups of groups, could clearly report that.
For instance, in case of Probe, I receive an error message from vtkXYPlotActor instead of probe itself. It is a bit confusing. To reproduce this behavior try simply: SphereSource->GroupDataSets->GroupDataSets->Probe
