[Paraview] Dynamically updating GUI list components

[Andy Heather]

Hi Clint,

I've attached a tar file with an example reader - it creates simple
client/server side plugins for files with extension '.test'. When you
select 'PVTestReader.test', the code will generate a cube.

The check-box on the properties panel switches between two data sets -
one with five arrays, and the other with ten. The list view on the
properties panel does not get updated, but if you go to the display
panel, you can see that the relevant fields have been generated by
looking at the 'color by' drop down selection.

Thanks,

Andy
