[Paraview] can't use saved states with Gaussian Resampling filter

[Celia Bremer]

Hello,

I have a problem with the Gaussian resampling filter that happens only when I load a state. My pipeline is data (polydata, points on an unstructured grid) -> Gaussian resampling filter -> IsoVolume. If I'm starting from scratch, get the data in via "open", and then apply the filters, I have no problems. If I then save the state and reopen it later, 2 things happen:

1) When I click on the eye next to the Gaussian resampling filter to make the result visible, I get an error message like

ERROR: In ..\..\..\..\src\ParaViewCore\ServerManager\vtkSMEnumerationDomain.cxx, line 75
vtkSMFieldDataDomain (000000000FBC65E0): Invalid idx: 0 

The number in parenthesis changes but the rest is the same every time. After the error pops up, the results of the filter become viewable, though. I don't get this error if the Gaussian splatter filter is visible when I save the state, but the second (more important) problem happens regardless.

2) If I set the resampling grid to 300x300x300 or above, when the green bar gets to 95%, my computer freezes. I can move the mouse but everything else becomes unresponsive. I can't even bring up task manager and I have to hold the power button to restart.

The error message is no big deal, but the other thing means I can't save my work, I have to re-do it from scratch every time. I would appreciate any help.
