[Paraview-developers] Disabling a programmable filter in pipeline

[Joachim Pouderoux]

Hello,

There is no way to do such a thing in ParaView.
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.
