<p class="MsoPlainText">Have been tweaked to actually trigger a modified on the proxy, and when the push to the server is made, the vtkObject has a modified triggered. I don’t think the SMProperty on its own would do that. No doubt you would know how to manage
it, but I found that having a CommandProperty allowed me to encapsulate what I wanted without affecting anything else.<o:p></o:p></p>

<p class="MsoPlainText">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?<o:p></o:p></p>
