ajaxStatus for specific component only

问题

I'm using Primefaces 3.2 with JSF 2.0.

I'm using a

<p:commandButton action="#{myBackingBean.action}" value="press me" />

And this for ajaxStatus:

<p:ajaxStatus onstart="statusDialog.show();"
      onsuccess="statusDialog.hide();"
      rendered="#{myBackingBean.ajaxStatusRendered}"
      id="ajaxStatusField" />

    <p:dialog modal="true" widgetVar="statusDialog"
      header="#{myBackingBean.ajaxStatusHeader}"
      rendered="#{myBackingBean.ajaxStatusRendered}" id="ajaxPanel"
      draggable="false" closable="false">
      <p:graphicImage value="./images/ajaxloader.gif" />
    </p:dialog>

I've got lots of other primefaces components also on the same page, but I only want the p:ajaxStatus to render when this specific button is pressed. Any good solution to this? The ajaxStatus renders on every ajax event..

回答1:

If you have a few amount of buttons, you could set on them global="false" and leave the desired button without this setting.

This way all other buttons wouldn't trigger the p:ajaxStatus while the desired button would.
