    JSF Component binding with conversation scope seam component

    Ramazan YILDIRIM Newbie

      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?
