Custom Filter Properties do not match individual object properties
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When you are using the custom filter wizard to expose properties to the user, the names of the properties do not match those exposed in the GUI for those objects. Furthermore, the GUI components in the resulting object inspector don't match those of the original object.
For example, consider making a custom filter with a contour filter as part of it. You want to expose the "Isosurfaces" part of the GUI. In the wizard, this parameter is called "ContourValues", not "Isosurfaces". When you then apply the custom filter, you don't get the same isosurface selection widget that is available in the original contour filter. Instead, you get a set of line edits, one for each contour value that existed when first creating the filter, to edit the isosurfaces.
The cut and clip filters are actually much worse in this regard. I can't make heads or tails of the property names for the cut filter.
