[Paraview] Causes for multiple execution of RequestData in rendering Pipeline

[Moreland, Kenneth]

My guess is that somewhere in your RequestData method the algorithm is calling Modified on itself.  The call is probably indirect.  For example, if you are using any of the Set* methods defined by VTK macros, that will indirectly call Modified.

To check this, try printing out the time stamp (this->MTime.GetMTime()) at the beginning and the end of RequestData.  It should be the same.  If not, narrow down where it is changing.
