[Paraview] pqViewManager in Clone2

[Utkarsh Ayachit]

That should work. Are you trying to call loadData() in the constructor
of your mainWindow class by any chance? If so that's too early, since
ParaView initialization code hasn't yet had the opportunity to read
the xml configuration files to initialize supported reader types etc.
You may want to use a timer to call the code after sometime.
