    rich:tabPanel lazy evaluation (M5)

    Dmitry Shultz Novice

      Hi All,

       

      I have a tab panel with several tabs, something like this:

       

      <h:form>

              <rich:tabPanel switchType="ajax">

       

                  <rich:tab header="Tab 1">

       

                      <a4j:repeat value="#{component1.items}" var="itm">

                              ... 
                       </a4j:repeat>

       

                  </rich:tab>

       

                  <rich:tab header="Tab 2">

       

                     <a4j:repeat value="#{component2.items}" var="itm">

                              ... 
                       </a4j:repeat>

       

                  </rich:tab>

       

              </rich:tabPanel>

          </h:form>

       

      Currently, the content of all tabs is evaluated when tabPanel is rendered, but I want to postphone  the #{component2.items} evaluation (because tab2 has some heavy processing and should be initiated only when it is really rendered).

       

      What tools are available to achieve it?

       

      Thanks,

      Dmitry.
