      Hi,

       

      i would like to reRender an modal panel before it get opened.

       

       

      {code:xml}
      <h:graphicImage rendered="#{model.available}" oncomplete="Richfaces.showModalPanel('#{id}');" value="${resources.image('changeTab')}">
           <a4j:support event="onclick" bypassUpdates="true" status="waitStatus"/>
      </h:graphicImage>
      {code}

       

       

      I´ve tried it like this, but i´ve a performance problem with this solution. It takes about 2 before it get opened.

      I´ve also tried to remove the status, but that´s not really the performance problem.

       

      What would be the right way to do this?

          oncomplete is not a attribute of h:graphicImage ... try this
          

           
          

          <rich:modalPanel id="dialog">
          

            foobar ...
          

            <h:outputText value="#{bean.foobar}"/>
          

          </rich:modalPanel>
          

           
          

           
          

          <a4j:form>
          

            <h:graphicImage rendered="#{model.available}" value="#{resource['foobarimage']}">
          

             <a4j:support event="onclick" 
          

                          reRender="dialog" limitToList="true"
          

                          oncomplete="#{rich:component('dialog')}.show()"
          

                          status="waitStatus"/>
          

            </h:graphicImage>
          

          </a4j:form>
          

           
          

          if the user click on the image a ajax request starts ... the ajax-response updates the dialog
          

          and the js-handler (oncomplet) open the dialog. you can also reRender only the inner part of the
          

          dialog but I'm not sure if this is faster/better than rerender the whole dialog .. maybe in some
          

          szenarios (dialog should stay open etc.) the reRender of the dialog-content is better
          

           
          

          regards

            Thnx, i´ve recognized my mistake before but thank you anyway!

             

            I´m reRendering now the inner part of the dialog, i think for the performance it´s about the same.

             

            Do you know, is there a possibility in richfaces to limit the request parameters.

             

            For example, i only want to submit a part of the form, i know with a4j:region i can control the server side,

            but i also want to limit the request parameters itself, that for example not the full form is submitted, only 1 field.

            Is there any possibility to do this, without a javascript "hack" ?
