<a4j:poll> Render whole page problem

sandrokg Sep 15, 2010 9:49 AM

I have <a4j:poll> and <rich:extendedDataTable> on xhtml page. My problem is that <a4j:poll> renders whole page, and <rich:extendedDataTable> calls data model on <a4j:poll> interval.

Does anybody knows issue for my problem?

I also tried to put <a4j:poll> into <a4j:region> and it doesn't work.

<a4j:region id="region" renderRegionOnly="true" >
    <h:form >
        <a4j:poll id="poll" interval="1000" enabled="true"
            reRender="grid" limitToList="true" ajaxSingle="true" />

</h:form>
<h:form >
    <h:panelGrid styleClass="alert-grid" columns="1" id="grid" width="100%" >
        <h:outputText value="#{applicationAlertsMB.datum}" />
        <a4j:commandLink styleClass="alert-link" id="link"
            oncomplete="#{rich:component('allMessagesPanel')}.show()"
            rendered="#{applicationAlertsMB.alert}"
            action="#{applicationAlertsMB.turnOfAlert}"
            reRender="allMessagesPanel">
            <h:graphicImage styleClass="alert-image"
                value="/images/icons/transparent/transparent-image-32x32.png" />
            <h:outputText id="serverDate" styleClass="alert-text"
                value="#{messages.global_alert_message}" />
        </a4j:commandLink>
    </h:panelGrid>
</h:form>
</a4j:region>

Hi Sandro
Try This

    <h:form >
        <a4j:poll id="poll" interval="1000" enabled="true"
            reRender="grid" limitToList="true" ajaxSingle="true" />

</h:form>

<a4j:region id="region" renderRegionOnly="true" >
<h:form >
    <h:panelGrid styleClass="alert-grid" columns="1" id="grid" width="100%" >
        <h:outputText value="#{applicationAlertsMB.datum}" />
        <a4j:commandLink styleClass="alert-link" id="link"
            oncomplete="#{rich:component('allMessagesPanel')}.show()"
            rendered="#{applicationAlertsMB.alert}"
            action="#{applicationAlertsMB.turnOfAlert}"
            reRender="allMessagesPanel">
            <h:graphicImage styleClass="alert-image"
                value="/images/icons/transparent/transparent-image-32x32.png" />
            <h:outputText id="serverDate" styleClass="alert-text"
                value="#{messages.global_alert_message}" />
        </a4j:commandLink>
    </h:panelGrid>
</h:form>
</a4j:region>

or you remove the region if this is not needed. Because a region
limits the part of the component tree to be processed on the server side when ajax request comes. Processing means invocation during Decode, Validation and Model Update phase. Most common reasons to use a region are:
avoiding the aborting of the JSF lifecycle processing during the validation of other form input unnecessary for given ajax request;
defining the different strategies when events will be delivered (immediate="true/false")
showing an individual indicator of an ajax status
increasing the performance of the rendering processing (selfRendered="true/false", renderRegionOnly="true/false")

I tried it but it doesn't work.
I made new project and made only one page with poll and extendedDataTable, and there poll works fine, it doesn't render whole page, but if I copy that page into my original project it renders whole page. I checked libraries, both project have the same libraries.

What could be the problem?

Do you use any PhaseListener?

Do you handle GET requests?

if you have the code written in PhaseListener to handle GET requests, change the name of the jsp/ xhtml to some other name
and the issue should be fixed.

if not fixed,
please tell me
1. are you using JSP/ XHTML
2. name of the XHTML/ JSP
3. are you handling any GET requests?

I have the same issue lastweek but solved

Hi,
     I don't use PhaseListener, and I don't handle GET requests?
1. I am using XHTML.
2. whitch name of xhtml?
3. I am not handling any GET requests?

Do you think the problem is in web.xml, could there be a problem.

This is my web.xml

Problem still exists. If anybody knows how to solve this problem, please write solution.

Removing c:if tag solves problem if there is no dataTable within page.
Adding dataTable in page, problem apear again.
