[Paraview-developers] reload data

[Utkarsh Ayachit]

John,

(I haven't read the full thread so I may be missing something here, so
bear with me)

I am wondering what's the difference between a vtkSMCommandProperty
and vtkSMProperty? ParaView ServerManager does support using
vtkSMProperty directly for the purpose you mentioned. Maybe all we
need to add is suppose for create the "push button" when such a
property is found in the XML, isn't it?
