How do you "explicitly ask it not to"?  The timing of this work is being driven by a support case where the customer is having issues because of the sessionDestroyed call.  If there's a workaround, that would be great.

Would including HttpSessionActivationListener in the policy be helpful? Allow/disallow the passivation/activation callbacks that surround replication. Norman Richards told me earlier this year that those were causing issues for you guys, although you found a workaround.

The way I'd been thinking about configuring this is user specifies the classname of the policy they want to use in jboss-web.xml.  That would end up in the JBossWebMetaData for the war (WebMetaData in 4.x). If Seam had the ability to manipulate the metadata to specify an appropriate policy impl, that would be nice for users.

For AS 5 I was thinking of having the default policy impl be the Seam-appropriate one that disallows the sessionDestroyed callbacks on undeploy.
