Thanks for the clarification. I had tried this with the following error: vtkPythonProgrammableFilter (0x5458a60): Attempt to connect input port index 1 for an algorithm with 1 input ports.
I gather that 'SetNumberOfInputPorts()' should be called in the constructor of the filter, which I gather is governed by the xml file? If so, how can I expose editing of the algorithm constructor via the xml file?
