I want to execute a managed bean method when exiting the page, I use this code but the method is not executing when leaving the page. I am working with jdev 12.2.1.4.0. Can you help me plase:
<af:document smallIconSource="/resources/images/favicon.ico" title="Gestion des Pays" uncommittedDataWarning="on"
id="d1" onunload="performUnloadEvent"
clientComponent="true">
<f:facet name="metaContainer">
<af:resource source="/resources/utils.js" type="javascript"/>
</f:facet>
<af:messages id="m1"/>
<af:resource type="javascript">
window.addEventListener('beforeunload',
function (){performUnloadEvent()},false)
function performUnloadEvent(){
//note that af:document must have clientComponent="true" set
//for JavaScript to access the component object
var eventSource = AdfPage.PAGE.findComponentByAbsoluteId('d1');
//var x and y are dummy variables obviously needed to keep the page
//alive for as long it takes to send the custom event to the server
var x = AdfCustomEvent.queue(eventSource,
"handleOnUnload",
{args:'noargs'},false);
//replace args:'noargs' with key:value pairs if your event needs to
//pass arguments and values to the server side managed bean.
var y = 0;
}
</af:resource>
< af:serverListener type="handleOnUnload"
method="#{gestionPaysBean.clearFilter}"/>
