I like the idea. One possible problem that comes to mind is filters
that produce different output types based on the input. Will enough
of the metadata be passed through the pipeline before Execute() is
called for those filters to hint at their output type? Otherwise,
you'll be forced to hit Execute before adding any more filters.
Or, for that matter, what about filters which are disabled in the menu
when there is no scalar/vector/tensor data on their input?

Folks,
I have been investigating the ability to create pipelines in ParaView
without having to hit Apply at every single stage in the pipeline.
This would make it much easier to deal with really large data in a
usage scenario where the scientist is fairly familiar with the
visualization pipeline he's interested in setting up.
Following the recent changes to the ParaView ServerManager, the
ServerManager level requirement that filters need to be updated
before
connecting has disappeared. However, we still need to "Apply" to get
updated information about arrays etc.
After a couple on discussions with Berk and Dave, I've consolidated
the thoughts on a Wiki page. If any one has any thoughts to share, it
would be great.

Note that this is merely a concept. We have no plans of implementing
it in near future (3.12/4.0).
