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.
Talk to you later,
-Eric

Eric,
Sorry for taking time to get back to you - I wanted to verify with
the developers that this isn't expected behavior. You have
correctly found a bug.
I wrote this up as bug number 8494 in the Kitware bug tracker. I
used your very simple, excellent Point and Sphere source example
listed below. If I missed anything, please feel free to modify the
bug appropriately.
Alan

Eric,
I think we dealt with this problem since 3.4. I can't reproduce the
problem with your first set of instructions on cvs head. Do you mind
trying the cvs version?

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,
I was trying to replicate this bug, and cannot. Please give me
detailed
instructions on how to replicate it, and I will put it in the bug
tracker.
Better yet would be you putting it in the bug tracker.
I tried:
ParaView CVS trunk from late January, XP, non client/server.
Source/Box
Source/Wavelet
(Highlight Box) Filters/ Generate Ids (Highlight GenerateId and
Wavelet) Filters/ Group Datasets Clip I then see the Ids points data
as follows: Ids (partial)

Subject: Re: [Paraview] Losing data when clip multi-block
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.
It's much more likely to disappear when the data was generated by a
filter or brought in by a reader.
For example, if you generate a Box and a Wavelet source, grouping
and
clipping them won't lose any data, but if you run Generate IDs on
one
of them, then select GenerateIds1 second before grouping, then
clip, the "Ids"
point data disappears...
Thanks,
-Eric

Eric,
Does the loss of arrays happen even if you clip the orginal dataset
by itself (without grouping it using the group filter)?

Hello,
I'm creating a multi-block data set using the group filter and
then
clipping it. The results of the clip are always missing one of the
scalars associated with the second data set that I highlighted
before applying the group filter. This only seems to happen if one
of the data sets has multiple scalars or vectors associated with
it
-- if they each only have one, nothing is lost in the clip.
(ParaView 3.4 and CVS, OS X 10.5.6 and Windows XP 32-bit, no MPI)
I originally saw this with my own data, but I am able to easily
replicate this by creating two point sources. I apply the
Elevation
filter to the first. Then, to the second I apply Brownian Vectors,
plus a Calculator that computes the magnitude of those vectors. If
I highlight Elevation and then Calculator, then Group and Clip, I
lose the vector magnitude scalar at the Clip stage. If I highlight
the Calculator and then the Elevation, then Group and Clip, I lose
the elevation scalar.
Please let me know if anyone has any ideas about where this could
be coming from.
Thanks a lot,
-Eric
