[jboss-user] [JBoss Seam] - JSF Component binding with conversation scope seam component

[ryildirim]

I use JBoss 4.0.5, Seam 1.2.1 and a seam-gen generated application. My application uses ajax4jsf heavily and I suspect this problem might be related with the conversation propagation with the ajax4jsf requests. 

When I try to use component binding
<rich:dataTable value="#{girisHome.girisHarekets}" binding="#{ajaxSupport.dataTable}".....

and ajaxSupport is like

@Name("ajaxSupport")
@Scope(ScopeType.CONVERSATION)
public class AjaxSupport {
	private UIData dataTable;
......

The page loads okay for the first time, because it creates the non-existent conversation scoped ajaxSupport component and binds the jsf component to the dataTable property of the seam component.  However, subsequent request to the same page results in:

javax.faces.el.PropertyNotFoundException: /GirisEdit.xhtml @206,53 binding="#{ajaxSupport.dataTable}": Target Unreachable, identifier 'ajaxSupp

By the way, when I change the component's scope to SESSION everything works fine.

Below is how the request is triggered from the client. An ajax4jsf request.

<h:outputText id="urunAdiText" rendered="#{not girisHareket.active}" value="#{girisHareket.urun.urunAdi}">                    
              			<a:support event="onclick" actionListener="#{ajaxSupport.onClick}" reRender="hareketPanel"/>
              		</h:outputText>

Any ideas what's going wrong?
