reRender jsp:include

[furic]

Hello
I'm trying to reRender a4j outputPanel that contains jsp:include.
The content of outputPanel gets rerendered, but when i click on save button, the same view is rendered and action method is not called.
Suspect logs :

 <jsp:include page="${clientBean.addJSP}" />
 </f:subview>
</a4j:outputPanel>

<t:commandButton value="#{msg['save']}" action="#{clientBean.saveObject}"/>

What can be the problem?
Why "No serialized view found in server session!" ?
Thanks

More details:
When the page is loaded first time,
clientBean.getAddJSP() returns empty.jsp with no content inside at all.
When status is changed clientBean.getAddJSP() returns add1.jsp, add2.jsp ... addN.jsp according to selected status. This additional jsp gets reRendered OK, but click on save button works ONLY if i change status back to empty value (in this case clientBean.getAddJSP() return empty.jsp), in other cases i get "No serialized view found in server session!."
Can it be that when strusture of view has been changed (additional components were added) in ajax request, the view became invalid ?
Thanks
