Hi,<br><br>By using blibli->SetInputConnection( blabla->GetOutputPort( )) instead of old fashioned-methods, the error regarding missing connections disappears. However, errors remain : "vtkGraphAlgorithm returned failure for request". I didn't look at it.<br>
<br>BTW, I didn't understand the FillInputPortInformation implementation in your code. Why do you test the Superclass method before filling your information?<br><br>Jerome<br><br></blockquote><div><br>Jerome,<br><br>
I changed SetInput(...GetOutput()) to SetInputConnection(...GetOutputPort()) but I still get a bunch of these errors:<br> <br></div><div>vtkStreamingDemandDrivenPipeline (0x8eede78): Algorithm
vtkGraphAlgorithm(0x8eebee8) returned failure for request:
vtkInformation (0x8ee9ef0)<br>
<br>The FillInputPortInformation I had just taken from another filter - I don't know what that part was doing either. I removed it.
