Time for action – the Dialog component close event listener

Let us see how we can register a listener for the close event using the following steps:

1. Create a Dialog component and register a close event listener using the <p:ajax> tag:

   <h:form id="form3" style="width: 400px;">
     <p:messages id="msgs" for="SampleDialog"/>
     <p:panel header="Dialog - Close Event Listener">
       <p:commandButton value="ShowDialog" onclick="dlg3.show();" type="button" /> 
       
       <p:dialog id="SampleDialog" header="Sample Dialog" widgetVar="dlg3" width="300" height="50" 
             showEffect="bounce"  hideEffect="explode" closeOnEscape="true">
         <p:ajax event="close" update="msgs" listener="#{dialogController.handleDialogClose}"/>
         <p:outputLabel value="PrimeFaces Dialog"/> 
       </p:dialog>
     </p:panel>
   </h:form>

2. Implement the handleDialogClose() method to handle the close event:

   public void handleDialogClose(CloseEvent event) 
   {  
     String...
