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

I don't see an example that does exactly what you want.
But here's something that might work (untested).

<StringVectorProperty
        name="PhaseNameInfo"
        command="GetPhaseList"
        information_only="1">
        <StringArrayHelper/>
  </StringVectorProperty>

<StringVectorProperty
      name="PhaseName"
      command="SetPhase"
      number_of_elements="1">
     <StringListDomain name="operation">
        <RequiredProperties>
          <Property name="PhaseNameInfo" function="ArraySelection"/>
        </RequiredProperties>
     </StringListDomain>
</StringVectorProperty>

That's assuming your reader has a SetPhase function.
The PhaseNameInfo is used to get the list of available strings, by calling 
GetPhaseList which returns a vtkStringArray.
Note how the PhaseNameInfo is tied to the domain of the PhaseName property.
The PhaseName property is used to set the selection on the reader.
The GUI would give you a combo box to choose one string from a list.

StringArrayHelper is new and doesn't exist in 3.0.  You might be able to copy 
it from the CVS head, rename it and include it in your plugin.

This approach might be easier in the long run, as you'll have less code to 
maintain yourself.
