OK. What you describe is not part of the original posting of 6662, but I'll take your word for it that there is a larger issue encompassing both problems. Perhaps this is documented in the voluminous notes attached to 6662 that I'm not going to bother to read.

In the executive, there is a check for IsTypeOf(insert compound stuff here), and the test returns true when it gets temporal, but should be returning false because the filter wants multi-block - which is a sibling of temporal. 6662 is causing a great deal of errors related to temporal data and fixing it will also fix 9089 (at least I think so). 6662 really addresses 2 serious problems in my mind. One is the wrong type checks above, the second is the incorrect creation of Temporal types when not really needed. Although they are two bugs, I propose a pipeline /executive fix which should address both. On a side note. Does the original poster know that the temporalPathline filter already does what he wants? (build trajectories of particles etc?) - though not multi-block. JB Re: [Paraview] Problem with temporal filter and multi-block data I actually disagree with that statement. The issue with 6662 is that the pipeline is sometimes stuffing data in a vtkTemporalDataSet when it should not. If you look carefully at 9089, you will see that in fact the data is supposed to be in vtkTemporalDataSet; the downstream temporal interpolation filter will not work otherwise. The error occurs even when the data really should be in temporal form. In my mind 9089 is a fairly serious issue; the executive is failing to properly use a filter that does not directly support temporal data. Issue 6662 is just a minor inconvenience; as long as temporal data is being handled correctly, the only effect to the user should be an odd reporting of temporal data set in the information panel. -Ken On 6/2/09 12:57 AM, "John Biddiscombe" <biddi...@cscs.ch> wrote: This is yet another manifestatrion of http://public.kitware.com/mantis/view.php?id=6662 which I will try to look at this week or next. I'm linking the bugs. JB Re: [Paraview] Problem with temporal filter and multi-block data That clarified it. I am able to reproduce the problem now, and I see that it is in fact a bug. I submitted a report for this. http://www.paraview.org/Bug/view.php?id=9089 Thanks for bringing this to our attention. -Ken On 5/31/09 1:07 AM, "Christian Wellmann" <wellm...@ikm.uni-hannover.de> wrote: Hi Ken, the order of operations is: -load the data -attach the ExtractBlock to the reader -attach my temporal filter to the ExtractBlock filter If my data doesn't consists of multiple parts, so I don't have to use the ExtractBlock, my temporal filter works fine. christian 2009/5/29 Moreland, Kenneth <kmo...@sandia.gov>: > I am confused about the order of operations you are doing to get the error > (since it apparently only happens if you do things in a certain way).
