RichFaces4 popupPanel + a4j:poll

edilmar May 2, 2011 4:47 PM

Hi,

I have to create a page where the user clicks a button, a popupPanel is showed and a message should be updated at intervals. And after some logic stops, I have to hide the popup, like a "slow processing window" for better user interface. I implement a test in this way:

      <h:form id="formpoll">
        <a4j:commandButton onclick="#{rich:component('popup')}.show()" action="#{teste.initPoll}" value="Init poll/popup"/>
        <rich:popupPanel id="popup" autosized="true" width="400" height="80" moveable="false" resizeable="false">
          <f:facet name="header"><h:outputText value="Processamento" /></f:facet>
          <h:outputText id="datePoll" value="#{teste.msgPoll}" />
          <a4j:poll id="poll" enabled="#{teste.enablePoll}" interval="1000" render="datePoll" oncomplete="#{rich:component('popup')}.hide()"/>
        </rich:popupPanel>
      </h:form>

1. click button => show popupPanel => fine!

2. update msgPoll using a4j:poll => fine!

3. oncomplete doesn't wait for a logic to complete, it closes the popupPanel after 1000ms. How could I implement a way to automatically close the popupPanel after ending of process?

you can add action or actionListener to the a4j:poll and is in your code you can close the dialog when the response completes.

Hi Edilmar, could you please check progressBar [1] component, it might be useful in your use. You will then use onfinish handle for hiding the popup.

Hi,

The comp progressBar is not good for this situation.
I need to show a message at each X seconds, many and many times, until some logic is finished. Then, at this time, I need to close popupPanel. Because this I would like to know if there is a possibilty for Managed Bean to make a "inversion call" to browser, to close popup.

You would l ike to:

1. periodically update message in popup panel and then - after completion - close it
2. or only close popup after completion?

For (2) as a simpler case, you could use push facility - your client can be contacted through JMS.

Solution for (1) may be using a4j:poll with dynamically updated oncomplete method, something like:

<a4j:poll id="poll_message" render="message" oncomplete="#{not process.completed ? '' : rich:component('poll_message') + '.disable(); ' + rich:component('popup') + '.hide()'}" />
