In ParaView's collaboration support there's the notion of a master and<br>
everyone else. The first client that connects to the pvserver is the<br>
"master" by default. The master is the only one that should create new<br>
proxies. This doesn't preclude the other clients from not creating new<br>
proxies, but if they do, things start acting funny. Also all client<br>
have exactly the same views as the proxy. They can be showing a<br>
different camera, but not have different number of views or types of<br>
views etc.<br>

</span>There seems to be a bug where the ParaView client has trouble loading<br>
existing state from another client. It seems to work as expected if<br>
the "master" starts creating sphere etc. after the other client has<br>
connected.<br>
<span class=""><br>

<br>
</span>Same issue as (a).<br>
<span class=""><br>

<br>
</span>In this case your non-master example has created a view which is not supported.<br>
<span class=""><br>

<br>
</span>A bug in loading initial collaboration state.<br>
<span class=""><br>

<br>
</span>You're showing sphere in a view not known to master.<br>

<br>
</span>Proxies are being created before the session was "ready for use". Like<br>
I said, collaboration isn't being used actively in production so such<br>
issues are expected. Since I don't have active projects funding this,<br>
I will try to track down the bug exposed by (a) and give you a fix<br>
over the weekend if I can.<br>
