<p class="MsoNormal">So far so good, the gui does have the elements which are exposed, however the drop down box is empty and as far as I can tell the ContourProxy variable remains NULL. Presumably I have to create the vtkPVContourFilter object somewhere, however
I am unsure as to how/where.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can anyone provide some guidance on what steps I am missing?<o:p></o:p></p>

<p class="MsoNormal">Thanks.<o:p></o:p></p>
