Ques 5. What is a4j:commandLink in RichFaces?

The a4j:commandLink combines the standard h:commandLink with our own a4j:ajax. This not only reduces typing, but also inherits all a4j:ajax special options.

<a4j:commandLink value="#{constants.Label_DateUploaded}" action="#{handler.tableHeaderListener}" ajaxSingle="true" reRender="claimDocTable" onclick="loadClaimDocs()" styleClass="tableHeaderTxt" oncomplete="completeClaimRender()">

<f:setPropertyActionListener target="#{handler.sortField}" value="#{constants.Label_DateUploaded}"/>

</a4j:commandLink>

The rich:tooltip component creates a small non-modal pop-up that can be used to display additional information for nearly anything on the page.

<h:outputLabel styleClass="tooltipSpan">Use this to upload the documents selected for upload and their document properties to the document repository.<p>Shortcut: CTRL+SHIFT+U</p></h:outputLabel>

</rich:toolTip>
