[Paraview] Temporal collection problem

[Gottfried Necker]

Hello again,

I have to reply to myself. On friday I wrote the following mail:

Unfortunatly I was not able to provide a simple example to demonstrate the 
problem. But today I found one by modifying a Xdmf test case. The original is 
TetrahedronSpatialTimestep.xmf, the modified TetrahedronSpatialTimestep-
mod.xmf. The change is in the "Value" strings for the time. I deliberately 
added some decimal places. Using ParaView 4.3.1 I can step through all 3 time 
steps of the original case, but only through the first 2 of the modified.

My original problem also works if the time values are truncated to 4 decimal 
places.

Best regards,

Gottfried
