[Paraview] Fwd: PV 2.0.0 - problem w/ scalar range of contour filter?

[Randy Hudson]

Ignore my 2nd mail.  I HAD meant to describe using multiple contour filters of the dataset for the SAME scalar.

Also, I tested the downloaded executable of pv1.8.3 against that of pv2.0.0, and pv1.8.3 does not have the problem.  I tested it on the multicomb_0.vts data that comes w/ paraview.  I created 3 contour filters of the Density scalar, and in 1.8.3, the "Parameters" tab of each filter shows the same value range, whereas in 2.0.0, only that of the 1st contour shows that range.

(In the paraview whose source I'm working with, the range is "<ISO_ONE> to <ISO_ONE>".
