[Paraview] Bug Reading pvti Files?

[Kent Eschenberg]

Not sure if this is a bug. A new program of mine creates a pvti file that reference two vti files in the same directory. No errors are produced when PV reads the pvti file but the 2nd vti file seems to be ignored.

In the attached image the top object is what the pvti reader produces. A slice through just the right half has a min,max of 0,0.

The middle object results when only the "left" vti file is read; and the bottom when only the "right" vti file is read. Obviously the "right" file contains valid numbers.

The files without the binary parts are below. I hope someone can spot some simple mistake I've made.

OS: CentOS 5, 32-bit
PV: CVS downloaded June 25 at 4:42pm
Compiler: gcc 4.1.2
CMake: 2.4.6

This is a major problem for a project here and so all advice will be very much appreciated!
