Ajax richfaces tree problem

[ar_sahl]

Hello Every body.
I have a problem in using ajax switchType tree. I am using richfaces-api-3.1.1 version. I wrote the following code in jsp:

<rich:tree nodeSelectListener="#{marketViewBean.onSelectZone}"
 reRender="zonePanel" ajaxSubmitSelection="true" switchType="ajax"
 value="#{marketViewBean.node}" var="item">
 </rich:tree>

and I wrote a method with following signeture:

public void onSelectZone(NodeSelectedEvent event){}

but when a node is selected in the tree no event happens and the method is not called. When I change 'switchType' attribute to 'client' or 'server' it works currectly.

Can anybody help me with this issue?

Maybe ajax filter is not configured well ?
