It's much more likely to disappear when the data was generated by a filter or brought in by a reader.

Re: [Paraview] Losing data when clip multi-block
Thanks a lot, Alan. This was driving me nuts that nobody could reproduce it! :) For now I wish I could predict which variable was going to be lost so I could at least create a sacrificial array that could disappear and leave my real data intact. I also wish I knew the difference in Berk's build that won't reproduce my first example since I still see the data loss on today's CVS. I'm trying an MPI build in case there would be a difference in how multi- block data sets are handled, but I know that's probably grasping at straws... Anyway, thanks for filing the bug and I'll take a look at it later to see if I can add anything.

Re: [Paraview] Losing data when clip multi-block
Eric et al, I recently had a problem where a filter opreated normally when used normally, but when someone put a calculator in front of it, it stopped working. The filter in question instantiated other filters internally. I tracked to the problem down to this. Calculator calls SetActiveScalars(New data) another filter later does a PointData()-PassData(blah) -SetActiveScalars(More New data) And the New data from before was lost. I do not like this SetActiveScalars function because it replaces (not adds) whatever scalar was there before. I cnaged the offending filter (in this case vtkSurfaceVectors) on my copy to do PointData()-PassData(blah) PointData()-AddArray(newData); PointData()-SetActiveScalars(newData-GetName()) or something like that (from memory). I have no idea if this is related to your problem, but I just thought I'd vent my spleen and start a campaigh to remove this SetActiveScalars(...) call as it is just rubbish. (At least it should be modified internally to not remove the old active slalars if they are are about to be wiped) JB Hey Utkarsh, No, I've never seen the clip lose data on one dataset by itself. The other interesting thing is that I can't always get this data loss to happen if the data was generated as part of a source from the Sources menu.
