[Paraview] Event triggered by cell/point array status change?

[Sven Buijssen]

Hi,

Could someone please tell what the name of the event is that is
triggered in ParaView (top of cvs build) when the cell/point array
status (properties tab of the object inspector) is changed after a file
has been initially loaded and one hits the "Apply" button again?

It's neither RequestData nor ProcessRequest, at least not for my custom
reader which is based on the vtkUnstructuredGridAlgorithm class. It does
work, though, for the ExodusIIReader and other built-in readers.

Thanks a lot.
Sven
