UndoRedo states are not meant to loaded across different sessions. If
loaded in the same session such ID conflicts should not occur.

What state loader are you using? If you use vtkSMPQStateLoader or
subclass it should not try to reassing IDs.

Hello,
I'm also facing a related problem when I save/restore vtkSMProxy's.
The proxy ID is stored in the XML file. So when I reload the proxies,
the StateLoader attempts to recreate the proxy with the same ID as
before. But because I'm running a new ParaView session, sometimes the
saved ID has already been reserved by another object in the current
session, causing a collision.
When this happens, ParaView aborts inside the function:
vtkClientServerInterpreter::ProcessCommandAssign(const
vtkClientServerStream& css, int midx)
The error message is "Attempt to assign existing ID".
Has anyone else ever dealt with this before? Is there a known
workaround? Am I completely off base?
Thank you!

Thank you Utkarsh !
it works but I have some problems like:
- after restoring the proxy, changing some display properties in
Paraview has no effect (like color ...)
- only the display properties are saved/restored. (variables in
object inspector "properties" tab are not restored)
It's probably the way that I'm casting the source proxy and some
staff like that.
I'll try to solve these problems and let you know.
thank you !

Here's one way of doing it:
vtkSMProxyManager* pxm = vtkSMObject::GetProxyManager();
vtkSMProxy *tempProxy = pxm->NewProxy(
src->GetXMLGroup(),
src->GetXMLName());
tempProxy->Copy(src);
....
src->Copy(tempProxy);

tempProxy is just a proxy I created using:
vtkSMProxy tempProxy = vtkSMProxy::New();
I am trying to save/restore all the object properties displayed in
the object inspector.

Nehme,
What properties are you changing/trying to restore? Is
"tempProxy" of the same type as "src"?

Hello,
Sorry I missed a few commas in the last message. this is the
correct one:
I am looking for a way to save a proxy properties and restore it
later.
The only way I found is by saving and restoring the state using:
virtual vtkPVXMLElement* SaveState(vtkPVXMLElement* root);
virtual int LoadState(vtkPVXMLElement* element,
vtkSMStateLoaderBase* loader);
I don't want to use LoadState because this method create a new
proxy. I just want to restore all properties to the existing proxy.
There is also a method called Copy (void Copy(vtkSMProxy* src),
this method will copy all src properties to another proxy:
//copying properties to tempProxy
tempProxy->Copy(src,0,vtkSMProxy::COPY_PROXY_PROPERTY_VALUES_BY_CLONING);
I tried to change some display properties in Paraview and then
restore using:
src->Copy(tempProxy,0,vtkSMProxy::COPY_PROXY_PROPERTY_VALUES_BY_CLONING);
src->UpdateVTKObjects();
but nothing is restored ! why? Is there any other way to do that?
(suppose that I have only on source)
Thank you
