[jboss-user] [JBoss Seam] - socket write error with Seam Remoting

[scotto]

I have recently migrated from JBossAS 4.0.4.GA/Seam 1.0.1.GA to JBossAS 4.2.0.CR1/Seam 1.2.0.PATCH1 and am getting a new exception.

My web interface uses Seam.Remoting.subscribe() to asynchronously subscribe to JMS messages. This functionality is working correctly, however if I navigate away from the page, I get the following server exception after a short period of time:

I think it might have something to do with the server trying to respond to an old browser long-poll request that has since been terminated on the client side (i.e when the user navigates to another page)?

This same code used to work fine with Seam 1.0.1.GA however. Any ideas what is causing this?

Thanks,
Scott
