Summary

0007323: First Cell Property (Data Array) Not Accessible By Filters Until Choosing Another Property First

Description

Steps to reproduce the problem:

1) Create a Box
2) Apply the Box
3) Create a Calculator on Box
4) Create a Cell property (I used 4*5 as my calculation test)
5) Apply the Calculator
6) Create any filter (I'll use Threshold for a good example) on the Calculator that needs to use the Cell property
7) The Threshold filter thinks that the data range for the property is 0 to 0, and both sliders are locked against the left
8) Click Apply, you will get nothing (since a range of 0 to 0 gives nothing)

Steps To Reproduce

Additional Information

This problem can be avoided in the case of threshold only if there are other properties. You can pick one of the other properties in the drop down, then re-pick the first cell property; its range will now be correct.

However, you won't always have another cell property to flip around with, and in those cases your filter in #6 will fail when clicking apply. We have tested this with other filters than Calculator and Threshold and get the error message:

ERROR: In ..\..\..\VTK\Filtering\vtkAlgorithm.cxx, line 306

Tested on Windows XP 32-bit with development paraview. Single-process mode.
