[Paraview-developers] Animation: spreadsheet view not synchronized with table

[Cornelis Bockemühl]

Hello,

I just see that in the RequestInformation function I am adding the
steps and range info only to the information object that I receive
through GetInformationObject(0), but then I am working also with the
objects 1, 2, etc.: Maybe this is the thing that I should change??

I will immediately try this in my code...

Regards,
Cornelis

type="None" port="..." />). This works nicely so far.

with empty tables. If I open now a spreadsheet view and look at any
of them this correct. But if I now press "play" and go from step to
step, only the "unstructured grid" gets updated, not the
spreadsheet view.

"play". With that I am at the last step, and opening a spreadsheet
view for the tables gives me the full tables - again correct. But
again: if I go back in time, the tables stay as they were initially
(i.e. full).

being shown immediately and the second only "on demand". Indeed I
could almost reproduce the behaviour: the first table does what is
expected, but the second not. Only difference with my full case:
the second table NEVER shows anything, no matter if I press the
"play" button earlier or later!

bug that needs to be fixed? (Actually I hope for the first because
then I can quickly apply the fix in my own software and I am
fine!...)

plus a screenshot that illustrates the case where the second table
shows some content only in the properties panel (left), but not in
the spreadsheet view (right).
