p:ajax dead after some time

[PGoldwin]

In my startup screen there is selection between "Login" or "Register". Selecting any uses p:ajax to show login/register fields.

Code: Select all

<h:commandLink type="submit"  value="Logga in"  styleClass="link-button">
	<p:ajax event="click" listener="#{loginTypController.ajaxLoginSelected}" update="sectionSelection"/>
</h:commandLink>

If I leave the startup page for say 20 minutes the p:ajax event is no longer working. F5 for refreshing the page and now is it working again.

Any suggestions how I can solve this problem?

Env:
- Liferay 6.2
- JSF 2.2 portlet
- Primeface 6.2

Did you check for errors? Network tab in the console, server side logging? And more... I suspect a session timeout. Always good to add an ajax error handler.

No errors in Chrome console log (F12).

How do I add ajax error handling?

[PGoldwin]

I added error handler:

Code: Select all

<p:ajaxExceptionHandler type="javax.faces.application.ViewExpiredException" update="exceptionDialog" onexception="PF('exceptionDialog').show();" />

Nothing was shown by error handler.

Now I payed more attention to Tomcat log:

09:57:27,554 ERROR [ExceptionHandlerBridgeImpl:81] viewId:/views/loginTypIntro.xhtml - View /views/loginTypIntro.xhtml could not be restored.

Any suggestions?

Post the 'error' in google. Not a PrimeFaces issue but a generic JSF one. Can be multiple causes... From a plain session timeout to more complex things (to little views in cache etc...)

Thanks for pointing me in the right direction. Clumsy of me not to google the error. Usualy this is done but since I found the error message after first post was made I forget that step.

Problem not solved yet but now I know where to look.
