      When i use the a4j:commandButton to call a action that foward to other page using the navigation-rule, my rich:toolbar in the new page stop to work in Firefox.

      When a change for h:commandButton everything works fine in IE and Firefox.

      I'm using:

      Richfaces 3.1
      Facelets
      JSF 1.2

      What's the problem with the a4j:commandButton ?

          Hello,

          I have the same problem.

          -JBoss-Portal 2.6.4
          -RichFaces 3.2.0.GA
          -JBoss Portletbridge 1.0.0.B1
          -Facelets
          -SUN RI 1.2


          This example don't works with a4j:commandButton, but works fine with h:commandButton on both browsers.

          <a4j:commandButton action="MAIN" value="Back" />


          <navigation-rule>
 <from-view-id>*</from-view-id>
 <navigation-case>
 <from-outcome>MAIN</from-outcome>
 <to-view-id>mainworld.jsf</to-view-id>
 </navigation-case>
</navigation-rule>

            I try the same approach with Richfaces 3.2 and the problem persist.

            Why the a4j:commandButton don't work ?

              when you use navigation rules in a4j:command* components - you should place

              <redirect/>

              for the navigation case in faces-config defned.

                Hy ilya!

                Is there a limitation in navigating with a4j:command* components when using redirect-Tag? Because it seems to me that i loose my faces-messages, when I'm doing it this way.

                Without redirect in nav-rule, i have problem with styles of richfaces-components, when I handle the site-navigation via a4j.

                  When you are using redirect, you make separate request to a new page. That results in loss of Faces Context with all its bells and whistles.

                    thanks for the clarification maksim!

                    But what can I do, in my situation?
                    I have a site, which contains a4j:commandButton and action calls an execute-method. this methods executes an processaction and after this execution, it checks if process is finished or not:
                    -) if process is not finished, new content for inputs is loaded from db, an null will be returned to handle next task of process - so i will stay on the same site and site-content is rerendered.
                    -) if process is finished, I'm generating an facesMessage, and then sending a returnvalue (defined in one of my nav-rules) to jump to another site.

                    And here is the problem
                    -) if I do not use redirect-Tag in my nave-rule, i will loose the style of my richfaces-components on the other site (I don't know why).
                    -) if I use redirect-Tag in my nav-rule, i will loose the facesMessage, i generated in my action.

                    I can use normal h:commandButton without redirect-Tag in nav-rule for sure, but I want use ajax-navigation, because i stay several times on the same site, before jumping to the other.
                    But unfortunately I have no idea how I can achieve this with aj4:commandButton.
