    commandLink not working if rendered dynamically

    Damian Harvey Master

      I have a problem where the Ajax4JSF commandLink and commandButton don't work if they are rendered via an Ajax call. I'm using ajax4jsf-1.1.2-20070718.000117-113.jar and Seam 1.3.0ALPHA.

      I have created a simple test to prove this. My TestBean:

      package com.locuslive.odyssey.session;
      
      import org.jboss.seam.annotations.Logger;
      import org.jboss.seam.annotations.Name;
      import org.jboss.seam.log.Log;
      
      @Name("testBean")
      public class TestBean {
       @Logger Log log;
       private boolean toggle = false;
      
       public void sayHello() {
       log.info("*** Hello ****");
       }
       public boolean isToggle() {
       return toggle;
       }
       public void setToggle(boolean toggle) {
       this.toggle = toggle;
       }
      }

      My test.xhtml page:
      <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
      "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
      <ui:composition xmlns="http://www.w3.org/1999/xhtml"
       xmlns:s="http://jboss.com/products/seam/taglib"
       xmlns:ui="http://java.sun.com/jsf/facelets"
       xmlns:f="http://java.sun.com/jsf/core"
       xmlns:h="http://java.sun.com/jsf/html"
       xmlns:a="https://ajax4jsf.dev.java.net/ajax"
       xmlns:rich="http://richfaces.ajax4jsf.org/rich"
       template="/layout/template.xhtml">
      
      <ui:define name="body">
      <h:form>
      <a:log/>
       <a:commandLink id="sayHelloLink_1" action="#{testBean.sayHello}" value="Say Hello!" reRender="testDiv"/><br/>
       <a:commandLink id="toggleLink_1" action="#{testBean.setToggle(true)}" value="Turn on toggle" reRender="testDiv"/>
       <s:div id="testDiv">
       <s:div id="renderedDiv" rendered="#{testBean.toggle}">
       <a:commandLink id="sayHelloLink_2" action="#{testBean.sayHello}" value="Say Hello!" reRender="testDiv"/><br/>
       <a:commandLink id="toggleLink_2" action="#{testBean.setToggle(false)}" value="Turn off toggle" reRender="testDiv"/>
       </s:div>
       </s:div>
      </h:form>
      </ui:define>
      </ui:composition>
      


      If I click on the first SayHello link, the method in the TestBean is hit and the message prints out in the logs. If I click the "Turn on Toggle" link, my div displays. If I then click on any of the links that have been newly rendered they do not work.

      I have cranked up the log4j settings on my server and the big difference is that on the lines that work these entries appear:
      10:16:26,892 DEBUG [Contexts] found in event context: testBean
      10:16:26,892 DEBUG [RootInterceptor] intercepted: testBean.sayHello
      

      whereas they are not there when a rendered link is clicked. Does anyone know what might cause this? Is anyone else having problems with rendered links?

      Thanks,

      Damian.
