PV 3.4 Release and CVS both work. Time shouldn't make a difference.
Not sure at this point without seeing all your code. Maybe another set
of "eyes" can spot the difference.

Thanks for the code, but I am doing all you are doing... (except my
reader is static (no time), maybe this makes a difference?)
Are you using PV 3.4 or CVS?

At the top of RequestData() method how are you getting the output
object? Maybe that has something to do with it?
You can take a look at my code
<http://echo1.bluequartz.net/viewvc/CTMD/PVPhaseField/src/Readers/vtkH5PhaseFieldReader.cpp?view=markup

and compare with your own.

Thanks Mike,
Yeah, no doubt I am doing something wrong, but am clueless. At the
end
of RequestData
this->GetOutput()->GetExtent(extent);
gets a valid extent. But PV does not see it (and screws up some
filters).

As I do. Please, can you check if you see both extents and
bounds in
Information?

One more question: where do you derive your reader from

Thanks Mike, but this is exactly what I have.
Are you sure you see both bounds and extents in Information?

this->DataExtent[0] = this->DataExtent[2] =

What else then WHOLE_EXTENT, UPDATE_EXTENT and SetExtent
and do I
have
to fill in RequestInformation/RequestData of my plugin
reader
(derived
from vtkImageAlgorithm) in order for Paraview to see the
dataset's
extents? Only bounds are displayed in the Information tab,
while for
native file formats there is also extents. But when I
save the
file in
legacy format for a test the extent is written correctly,
so
it WAS
known to Paraview, only not displayed properly. What is
wrong?
