[Paraview] QListWidget Selection Issue

[Brian Panneton]

I got rid of the error "had to make up a value for selection" by adding
    information_property="w3_DataList"
to StringVectorProperty w3_lbData. I still can't get the SetDataArrayStatus
to be called correctly. It still seems to want to make argument 3 a string.
