[vtkusers] vtkProcessObject

[JEAN-EDOUARD COSTE]

Hi

I'm trying to make filters but i have a problem.

My pipeline is like this : Reader -> ExtractEdges -> Window
And i do some modifications of mesh with a vtkPointWidget.

To identify the problem i've copy vtkExtractEdges to myExtractEdges whith
the same source code, changing only the name.

 - With vtkExtractEdges, the update works right when a point is modified.
 - With myExtractEdges (with the same code !), the Execute() method is
executed on the beginning, but no update is done.

Would somebody have an explanation ?
