      <html>
       <head>
       <title></title>
       </head>

       <td><h:graphicImage value="/images/banner.jpg" /></td>
       </tr>
       <tr id="body">

       Este es el menu...
       </td>
       <td>
       <a4j:outputPanel id="wizard">
       <a4j:include id="i" viewId="b.jsp" />
       </a4j:outputPanel>
       </td>
       </tr>
       </table>
       </f:view>
       </body>
      </html>

          What the version of RichFaces (or Ajax4jsf you use)?
          What is the JSF implementation?

          Important points you miss:

          1. included code is the part of the whole page. So, there is no reason to have < html > < head > < body > there.

          2. No reason to point to the outputPanel with reRender attribute (unless you use very very old version of Ajax4jsf)

          3. Use context-related viewId. I.e. let it to be started with "/"

          In general, The code snippet of the #{bean.beanAction} and the navigation rules for the action outcome are missing to make any suggestion.

            Hi, i'm using the following versions:

            Myfaces-api ----> 1.1.1
            Tomahawk ----> 1.1.1
            RichFaces -----> 3.0.1
            ajax4jsf ------> 1.1.1

            This is my bean code:


            import javax.faces.context.FacesContext;
            import javax.swing.text.html.HTML;
            import org.ajax4jsf.ajax.UIInclude;

            public class bean {

            private String bannerUrl = "";

            public String getBannerUrl() {
            return bannerUrl;
            }

            public void setBannerUrl(String bannerUrl) {
            this.bannerUrl = bannerUrl;
            }

            public String beanAction()
            {
            this.bannerUrl = "next";
            return "next";
            }
            }



            This is my navigatios rules:
             <navigation-rule>
             <from-view-id>/a.jsp</from-view-id>
             <navigation-case>
             <from-outcome>next</from-outcome>
             <to-view-id>/c.jsp</to-view-id>
             </navigation-case>
             </navigation-rule>
             <navigation-rule>
             <from-view-id>/b.jsp</from-view-id>
             <navigation-case>
             <from-outcome>next</from-outcome>
             <to-view-id>/c.jsp</to-view-id>
             </navigation-case>
             </navigation-rule>

                Hi all, ?why nobody answer me?

                Please, i need your help to solve this issue, i no doutbs that the solution is trivial but the fact is that the a4j:include is not working for me.

                ?There are some constraints to use the a4j:include? The docs not specify this.

                ?Can i use a4j:include in my old Exadel Studio projects?

                ?The a4j:include only work with xhtml pages?


                I have several doubts about this component and the documentation not clarify at all any of these.

                I hope you can help me.

                  1) a4j:include hasn't anything special in usage. Docs describes the usage. Main points - navigation rules returned by ajax controls will be processed only for included content.

                  2) You may freely use it in any projects.

                  3) It isn't important xhtml or jsp or jspx you use.

                  Why are you use so old MyFaces Tomahawk and RF environment, is it your requirements? There can be some problems connected with old myFaces versions,
