    no ajax request generated

    jasper floor Newbie

      Hi all,

       

      I am trying to get rich:progressbar to work. Near as I can tell there are no AJAX requests generated. While I haven't exactly read the JS which is sent to the browser I'm fairly sure the JS is there. So that may suggest a clash with other js. I am not seeing any errors. I just see nothign happening. There is something happening since if I refresh the page the progressbar is actually showing progress.

       

      making an example would be fairly difficult as there are too many custom things going on. Obviously I have looked at those but I can't say whether they are intefering or not.

       

      (We actually do have a custom progressbar but that component seems to switch values it shouldn't in the backing beans. It was decided that it made more sense to use a component form a stable library rather than maintain our own.)

          Hi,

           

          First of all, is your rich:progressBar placed in form and set to use AJAX mode via attributes?

           

          Second, please add a4j:log to the page and check what's going on there.

            The progress bar is in the form. Ajax mode should be default but I have tried to set it explicitly to ajax. Also I have explicitly set enabled to true.

            a4j:log gives no output.

             

            this is a simplified version of the form:

             

            <jsp:root version="2.0"
                xmlns="http://www.w3.org/1999/xhtml"
                xmlns:jsp="http://java.sun.com/JSP/Page"
                xmlns:f="http://java.sun.com/jsf/core"
                xmlns:h="http://java.sun.com/jsf/html"
                xmlns:t="http://myfaces.apache.org/tomahawk"
                xmlns:a4j="http://richfaces.org/a4j"
                xmlns:rich="http://richfaces.org/rich"
                >
                <jsp:directive.page contentType="text/html;charset=UTF-8"/>
                <h:form >
                    <rich:panel style="border-style: none;padding: 0px;" styleClass="actionbox">
                        <h:panelGrid columns="3" rendered="#{!actionRequestController.hideActionBar}">
                            <h:outputText value="#{actionRequestController.jobName}" rendered="#{actionRequestController.jobRenderProgressBar}"/>
                            <pb:progressBar interval="1400" value="#{actionRequestController.jobPercentage}" rendered="#{actionRequestController.jobRenderProgressBar}" />
                            <h:commandButton value="stop" id="job" actionListener="#{actionRequestController.stopJobAction}" rendered="#{actionRequestController.jobRenderProgressBar}"/>
                        </h:panelGrid>
                    </rich:panel>
                </h:form>
            </jsp:root>

             

            but this is included in other files. It never gets called directly.

              I see that there's no pb:* prefix declared on the page.

                oops, sorry. Ignore the pb tag, that's our own component we want to replace. It should be rich:progressbar. I was running both components next to each other and in trying to anonymize and simplify it I made a mistake.

                    I made a test project to see if I could get progressbar working at all. I've include the file but basically:

                     

                             <a4j:log id="lolo"/>
                                <a4j:outputPanel id="asdf">
                                <h:outputText value="This is a text"></h:outputText>
                                    <rich:progressBar id="pb3" mode="ajax" minValue="0" maxValue="100" label="#{test.progress}" value="#{test.progress}" enabled="true" reRenderAfterComplete="asdf" rendered="true"></rich:progressBar>
                                </a4j:outputPanel>

                     

                    If you remove the outputText nothing happens whatsoever.

                     

                    with the outputText there are ajax request generated but nothing is happening.

                     

                    firebug console says:


                    $(this.id) is null
