Execute a method before loading of the JSF page or on unloading it

Hayfa

Hello,

I have in the code bellow the method "clearFilter" of "gestionPaysBean" executed on load of the JSF page:

 <af:serverListener type="onloadEvent"

            method="#{gestionPaysBean.clearFilter}"/>

  <af:clientListener method="onLoadClient" type="load"/>

  <af:resource type="javascript">

  function onLoadClient(event) {

   AdfCustomEvent.queue(event.getSource(),"onloadEvent",{},false);

   return true;

  }

  </af:resource>

How to change this code to make it executed before the load of page or on unloading the page? I am working with jdev12, java 8

Timo Hahn

User, tell us your exact JDev version, please!

I don't understand your question. You said that the code is executed on load of the page. Next, you ask how to do exactly that?

You tagged the question with 'javafx2'. However, you are using ADF tags. Is this an ADF app or not?

@Timo Hahn Yes, this is an ADF app. The version of JDdev is 12c. My question is how to change this code to get it executed when exiting the page.

Timo Hahn

User, there are 6 JDev 12c version available. Which one do you use?

@Timo Hahn The version of Jdev is 12.2.1.4.0. I try the method in the link you have sent but it doesn't work on unloading of the page.

Timo Hahn

You can look at https://docs.oracle.com/middleware/12213/adf/ADFUI/using-adf-faces-client-side-architecture.htm#ADFUI-GUID-745B60F4-87BE-49C0-A300-2DC5CECC6265

To my knowledge, there isn't a silver bullet solution working for all cases. As you did not disclose the full use case, it's hard to give more directions.

@Timo Hahn Thank you very much for your help, but it doesn't work.

How about the before load; wasn't that also needed?
