[vtk-developers] vtkProcessObject: cannot disconnect inputs

Dear developers,
Looking at +- line 154 of vtkProcessObject.cxx in method SetNthInput
(CVS VTK), we find the following:
else if(!input && num < this->GetNumberOfInputConnections(0)-1)
{
vtkErrorMacro("SetNthInput cannot set input index " << num
<< " to NULL because there are "
<< this->GetNumberOfInputConnections(0)
<< " connections and NULL connections are not allowed.");
}
I find this new behaviour a bit strange, because it prevents me from
arbitrarily disconnecting inputs from multi-input filters, for example
a vtkProbeFilter. Is the idea really that all outputs should always
be disconnected from "back to front"?
Thanks,
Charl
