where I also gave some links to previous threads.<BR>><BR>> Briefly, the

wrong!). You will have to<BR>> play with extent translators, as it had been
discussed in a related thread.<BR>><BR>> As it is not a bug, but a
normal consequence of the basic purpose of<BR>> ParaView, I didn't submit a
feature request. I also didn't try the "Extent<BR>> translator" hack used
in a provided plugin (sorry I cannot remember which<BR>> one, but you will
find it in the mailing list archives).<BR>><BR>> Best regards,<BR>>

Which filter is exhibiting this issue?<BR>>><BR>>> One potential
source for such behavior could be that the filter in<BR>>> question is
not updating the WHOLE_EXTENT key in its RequestInformation<BR>>>
implementation, and/or not updating UPDATE_EXTENT correctly in its<BR>>>
REQUEST_DATA implementation. As a result ParView is using the
original<BR>>> extents. But I'd have to look to verify this hypothesis.
