I disagree with your disagreement. TemporalDataset is a TypeOf
CompoundDataset. 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.<br>
<br>
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.<br>

<title>Re: [Paraview] Problem with temporal filter and multi-block
data</title>
<font face="Calibri, Verdana, Helvetica, Arial"><span
style="font-size: 11pt;">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.<br>
<br>
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.<br>

<br>
the order of operations is:<br>
-load the data<br>
-attach the ExtractBlock to the reader<br>
-attach my temporal filter to the ExtractBlock filter<br>
<br>
If my data doesn't consists of multiple parts, so I don't have to use<br>
the ExtractBlock, my temporal filter works fine.<br>
