I have a test.xhtml like this:

<h:body>

    <a4j:status name="statusSplash" onstart="#{rich:component('splash')}.show()" onstop="#{rich:component('splash')}.hide()" />

    <h:form id="formCad">

        <rich:popupPanel id="splash" modal="true" autosized="true" moveable="false" resizeable="false">

            <f:facet name="header"><h:outputText value="Some title" /></f:facet>

            <h:graphicImage value="/imagens/splash.gif" alt="Aguarde" />

            <h:outputText value="#{t.msgSplash} ..." id="msgSplash"/>

        </rich:popupPanel>

        <a4j:poll id="pollSplash" enabled="#{t.pollEnabled}" interval="1000" execute="nenhum" render="pollSplash,splash,msgSplash"/>

        <a4j:commandButton id="buttonSplash" value="Open Splash"

                                                action="#{t.openSplash}" status="statusSplash"

                                                execute="pollSplash"

                                                />

    </h:form>

</h:body>

When the user press button, a4j:status shows the popupPanel. I would like to change dinamically the outputText (with t.msgSplash) while some "slow" process occurs in the server. Something like: "Processing step 1...", "Processing step 2...", ... "Processing step X...".

Then, I made TesteController.java like this, setting msgSplash = actual datetime, just to test the environment:

package control.testes;

 

import SubMacroUtils.FormatDate;

import java.io.Serializable;

import javax.inject.Named;

import org.apache.myfaces.extensions.cdi.core.api.scope.conversation.ConversationScoped;

 

@Named(value="t")

@ConversationScoped

public class TesteController implements Serializable {

  private boolean pollEnabled;

  private String msgSplash;

 

  public boolean isPollEnabled() {

    return pollEnabled;

  }

 

  public void setPollEnabled(boolean pollEnabled) {

    this.pollEnabled = pollEnabled;

  }

 

  public String getMsgSplash() {

    msgSplash = FormatDate.getDateTime();

    System.out.println(msgSplash);

    return msgSplash;

  }

 

  public void setMsgSplash(String msgSplash) {

    this.msgSplash = msgSplash;

  }

 

  public String openSplash() {

    try {

      pollEnabled = true;

      Thread.sleep(10000);

      pollEnabled = false;

    } catch (Exception e) {

      e.printStackTrace();

    }

    return null;

  }

 

}

However, popupPanel shows just the first setup of msgSplash datetime, and never more change it. The a4j:póll didn't help too.

Any ideas to solve this?
