Well, some progress to report. I built a Seam "nightly" and redeployed my app, and things seem to be better. If I click like a "normal" user, things are fine, but if I go nuts and click the link a bunch of times, I get the locking error. My only guess is that there's a timing issue between my onslaught of requests and the lock releases, but that's a semi-educated and somewhat obvious guess. The upshot is that it's working well enough for demoing/testing, though I'd still like to get a real fix for it. Any pointers are appreciated. I have the Seam source checked out, so I can go diving through that, and, of course, if the issue lies with JSF RI, I can fix that (hopefully) in short order. Thanks. :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4083651#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
