[Paraview] Losing data when clip multi-block

[Eric E. Monson]

Hey Alan,

Are you seeing both the point and cell Ids arrays? When I do this I  
end up with only the cell Ids array -- the points one is missing.

Here's another one that loses a data array consistently:

Create a Point Source (100 pts, 10 radius)
Apply Elevation filter to points
Create a Sphere Source
Apply Curvature filter to sphere
Select Elevation then Curvature
Group
Clip
Gauss_Curvature is missing in Clip Information (only see Elevation &  
Normals)
(or, after deleting clip and group filters)
Select Curvature then Elevation
Group
Clip
Elevation is missing in Clip Information (only see Gauss_Curvature &  
Normals)

Any luck with that one? (I'd just like to hear that someone can  
reproduce the problem before I file a bug report...)

Thanks,
-Eric
