Summary0013688: Client/Server only: Incorrect coloring of data type long. Correct for same data if data type is float
DescriptionStart ParaView.
Connect to single process PVserver
Load attached file. Apply.
Color by: "material (float)"
Enable color legend visibility
=> Note: four clearly distinguishable colors used for 3D object
Color by: "material (long)"
=> Note: 3D object only colored in red - despite the fact that the underlying numerical values of "material (float)" and "material (long)" are identical, just the data type differs.

Does not happen in builtin mode with ParaView 3.14.1.
ParaView 3.98.0 RC3 client/server mode affects, too.

Issue (remember, only arises in client/server mode) ...
... presents itself with
* ubuntu-x64-nightlymaster-superbuild on Ubuntu 12.04 64-bit
* Lion-nightlymaster-superbuild

... does not exist with
* (debian-x32.kitware) nightlymaster-superbuild on Ubuntu 10.04 64-bit
* WinXP64-VS9-nightlymaster-superbuild on Win 7 64-bit
* WinXP32-VS9-nightlymaster-superbuild on Win 7 64-bit

Issue causes dashboard test pvcs.GMVReaderBasicRead-static to fail on Blight.kitware for ubuntu-x64-nightlynext-static

Once resolved, ParaViewData/Baseline/serverGMVReaderBasicRead.png and ParaViewData/Baseline/serverGMVReaderBasicRead_WithVisitBridge.png (as of commit 48d309b389738ec) should get updated such that the images match ParaViewData/Baseline/serverGMVReaderBasicRead_WithVisitBridge_1.png

Developer Note: The problem also goes away is "Remote Rendering" is enabled. Thus we can conclude that the "material (long)" values get "corrupt" when the data is delivered to the client.

If we look at the "cell data" in a spreadsheet view, we see that the data for material (long) is totally corrupt.

The problem is with vtkDataReader not able to reader binary files that contain 8-byte "long" values. The reader assumes long with be 4-byte long which is true with Windows and 32-bit linux machines and not on 64-bit linux/mac machines. That explains why the tests fail on the some dashboards and not on others.
