    MyFaces, Facelets and Ajax4JSF

    Thiago Freitas Newbie

      I am trying to use a4j:support to reRender a componnent when a field is filled.
      The componnet to be rerendered does not is reRendered...
      I already tested my code without Facelets and it works ok...
      So, can anybody that already used ajax4JSF with Facelets help me?

      Thanks!

             <description>
             Due to the manner in which the JSP / servlet lifecycle
             functions, it is not currently possible to specify default
             welcome files for a web application and map them to the
             MyFacesServlet. Normally they will be mapped to the
             default servlet for the JSP container. To offset this
             shortcoming, we utilize a servlet Filter which examines
             the URI of all incoming requests.

              I resolved the problem!
              Just changing the ajax4jsf version
              :P

              Thanks!
