[Paraview] Displaying a List of Strings in a popup [ParaView 3]

[Mike Jackson]

Ok, so we tried this approach (vtkStringArrayHelper) but when we run  
ParaView we get the following error:

ERROR: In \Development\ParaView3\Servers\ServerManager 
\vtkSMProperty.cxx, line 449
vtkSMStringVectorProperty (040D0930): Could not create object of  
type: vtkSMStringArrayHelper. Did you specify wrong xml element?

ERROR: In \Development\ParaView3\Servers\ServerManager 
\vtkSMProperty.cxx, line 449
vtkSMStringVectorProperty (05490D60): Could not create object of  
type: vtkSMStringArrayHelper. Did you specify wrong xml element


Is there some where we need to Register the vtkStringArrayHelper  
class? or are we really barking up the wrong tree?
