a4j:status not working after reRendering

[pchauviaux]

Hello,

In our project, the a4j:status is working only the first time. The following times, it is not working anymore (except if we do a refresh). I have done a small test (based on the showcase's example) and I have seen that the problems came after a reRender has been done.

We are using Richfaces 3.3.3 Final.

Here is the sample code I used to reproduce the problem:

<ui:composition xmlns="http://www.w3.org/1999/xhtml"

      xmlns:ui="http://java.sun.com/jsf/facelets"

      xmlns:h="http://java.sun.com/jsf/html"

      xmlns:f="http://java.sun.com/jsf/core"

      xmlns:a4j="http://richfaces.org/a4j"

      xmlns:rich="http://richfaces.org/rich">

    <h:outputText value="Ajax  Status:"/>

    <a4j:status id="commonstatus"  startText="In progress..." stopText="Complete"/>

    <br />

    <rich:spacer height="5" />

    <h:form>

          <a4j:commandButton eventsQueue="foo" value="Ajax Request" reRender="testR"/>

          <br/>

          <br/>

          <a4j:outputPanel id="testR">

                    Test panel

         </a4j:outputPanel>

    </h:form>

</ui:composition>

Do you know a way to make the a4j:status work even after a reRender?

Remark: the problem appears also if there is a rich:messages on the page, but it could be solved by adding: ajaxRendered="false".

Thanks in advance.

Is it not working once you click on the button after reRender?

[pchauviaux]

Exactly. The scenario is:

- I access the page for the first time

- I click on the button and the status is working correctly

- if I click a second time on the button, it is not working anymore (because there was a reRender - if you remove the reRender, it works correctly but I need it in my application of course)

If I refresh the page, it will work again.

why do you want to reRender '<a4j:outputPanel' component which always reRenders (all components inside it) by default.

The <a4j:outputPanel> component is used when one or more components should be always updated. The component job is similar to that the "reRender"attribute does, but instead of specifying a comma separated list of components it wraps the components to be updated. This could be useful in cases when some components aren't rendered during the primary non-ajax response.

[pchauviaux]

It was just an example here, but probably not the best, you are right. But it would happen with other components as well.

For example, we also have the problem if we have a <rich:messages> tag on the page, but the problem disappear in this case when we add the attribute "ajaxRendered=false".

I finally found a solution to the problem. If I use this code for the a4j:status, using the "onstart" and "onstop" attributes, it works correctly:

<div id="statusMessageId" class="statusMessage" style="display:none;">

                              <div style="text-align:center;margin-top:400px;"><img src="ajax-loader.gif" /><br/>#{msgs.page_loading}</div>

</div>

<a4j:status onstart="jQuery('.statusMessage').show();" onstop="jQuery('.statusMessage').hide();"/>
