[Paraview-developers] state file and int list

[Utkarsh Ayachit]

I suspect the problem is with the hooking up of the property and the widget.

1. ensure that pqPropertyLinks is setup correctly so that
servermanager-property and teh Qt property are linked correct
2. ensure correct signal is fired with the widget is changed by the user
3. add break points in getIds to confirm that it gets called when user
changes UI and its returning correct values.
