Question: What is a4j:status in RichFaces?Answer: The a4j:status component is an indicator of an Ajax request. It has two states: start and stop. The start state indicates that an Ajax request is in progress. When an Ajax Response is returned, the component switches to the stop state. Give a loading progress on a ajax call:<rich:modalPanel id="statusModalPanelId" autosized="true" resizeable="false"> <h:graphicImage value="/views/images/loading.gif"/> <a4j:status id="statusId" onstop="Richfaces.hideModalPanel('statusModalPanelId');"> <f:facet name="start"></f:facet> </a4j:status> </rich:modalPanel> |
