"Input" and "Source" names are hard coded for multiple input filters
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Multiple input filters must have their input properties named "Input" and "Source" in filters.xml. If they are not named this way they apear grayed out in the paraview menus. This name scheme makes sense for most of vtk's multiple input filters but doesn't make sense for all multiple input filters. In some cases having the inputs named "Input" and "Source" make things more confusing as that pattern doesn't fit the filters operation.
