    <a4j:param>

      Hi,

       

      I use RichFaces 4.0.0 on the jBoss 6.0.0.Final.

       

      I'm just a beginner and try to deliver values from JSF to a Bean with the <a4j:param />, but that doesn't work.

       

      The example from the RichFaces Showcase (http://richfaces-showcase.appspot.com/richfaces/component-sample.jsf?demo=param&sample=clientParam&skin=blueSky) doesn't work either. There is no Error, but the values in the Bean don't change.

       

      Can somebody help?

       

      Thanks!

          hi morphie,

                TRY THIS....

          its the same code with little modification and the one thing you should do is make sure you have downloaded and added all jars for richfaces to act accordingly...

          Dont forget to add this particularl external jar to your project... http://www.java2s.com/Code/Jar/b/Downloadbatikext161jar.htm  . download dis jar and work on your project.. it might help...

            Hi morphie,

             

            I suggest you to use most recent version of RichFaces, i.e. 4.2.2.Final and also newer JBoss AS, e.g. 7.1.1.Final.

             

            Regards,

            Palo

              For me it´s working ok using Richfaces 3.3.3.Final and JBoss 6.0.0, but if you want try using:

               

              <f:setPropertyActionListener value="John" target="#{userBean.name}" />
