<div>Hello,<br>
<br>
</div>
There is no way to do such a thing in ParaView.<br>
</div>
As a work around, what you could do is to transform your
filter in a 'identity filter' (returning input as output) in
the case the input data does not have the properties you need
to process the data.<br>

<br>
a programmable filter I'm working on requires a specific
cell data being<br>
loaded by the input dataset. Currently I'm checking in the<br>
RequestInformation function if it was loaded and show a
vtkErrorMacro<br>
if it doesn't exist. After that the filter is shown in the
pipeline and could<br>
be applied, which would result in another error.<br>
Is there any way to remove the filter from the pipeline or
disable the<br>
'Apply' button directly after showing a message ?<br>
<br>
Thanks,<br>
Björn<br>
