Question

Is there some way to end a conversation in Seam 2 when the user leaves the page? I know, that I can of course end a conversation in the navigation rules( see this post), but I want to end a conversation when the user enters an url in the address bar of the browser.

Could this be achieved via Javascript (for example with onbeforeunload)? But how to stop a conversation via javascript?

address bar of the browser.

onbeforeunload)? But how to stop a conversation via javascript?

You could use JavaScript to implement an onbeforeunload event and use AJAX to communicate the user leaving to the site and end all your conversations. However, I don’t recommend you this solution because you cannot rely on a event happening on the browser, Javascript is not a good option, since you can disable it client-side (Not only that, but the browser may crash, the network connection may drop, etc..)

I think an alternative aproach to do this is by setting a seam conversation timeout on the server. You can try and reduce the timeout in order to close inactive conversation faster, when the user leave your page.

Configuring the conversation-timeout period can be accomplished through the following in your components.xml:

<core:manager conversation-timeout="700000" />

Notice that conversation-timeout only affects background conversations, foreground conversation will only timeout when the session times out which is relevant for your requirements.
