Event on exit browser and end conversation

[cremersstijn]

Hello,

Is it possible to call a method on some bean when somebody closes the browser or goes to another site?

And how can you call a method when the conversation ends or timeouts?
I've tried this:

@Observer("org.jboss.seam.endConversation")
public void endConversation(){
     log.info("conversation ended");     
}

But it won't work.

You could use a (possible browser specific) javascript hook when the page unloads that does a remoting call.

There are separate events org.jboss.seam.conversationTimeout and org.jboss.seam.conversationEnd. I think the end-version is called only on explicit ending of the conversation. Idling leads to the timeout-version and eventually to a org.jboss.seam.pre/postDestroyContext.SESSION

I'm using richfaces, but how can you for example on a
body tag (which isn't a jsf tag) hang a remote call, i used to do this with a4j:support but this won't work on a not jsf-tag like body.

Something like

<script language="JavaScript">

  window.onbeforeunload = doRemoteCall;

  function doRemoteCall() {

    // do the seam remote call

  }

</script>

Of course all the general remoting stuff applies regarding setup and calls.

I have tried it this way:

@Observer("org.jboss.seam.conversationTimeout")
public void conversationTimeout(){
     log.info("conversation timeout");
}

But it won't work :(.

I've openened a new forum topic with a clearer title:

Look at the details of conversationTimeout.  The conversationTimeout only occurs for your conversation if a foreground conversation is accessed, your conversation is background, and the conversation-timeout period has elapsed since last access of your background conversation.

Have a look at the a4j:jsFunction tag from RichFaces, with that you should be able to do what you want. Combine that with the suggestion from Nicklas.

good luck

Thanks for your reply, but i think it impossible to call an event when some really leaves the website, because the unload event on the body is called many times during the application flow.

I'm trying to use a timeout instead, unless you have a wonderfull script for this event?

Hi

No wonderful script I'm afraid, but I googled this a couple of weeks ago out of curiosity and found things like this:

Seems like hacks are used to determine where the mouse is, or something similar.
Never tried any of it but it would be really interesting to know if you have any luck with this :)
