I am having the same problem with seam-gen code (The generate-entities function). I had the problem with seam 1.1.5 and it still exists in 1.2.
My work around at the moment is to just restart JBoss...this problem pops up for me after I have deployed/"seam restart" your app a few times to jboss.
Anyway if someone can find another solution to this (because it is fine for a live enviroment where you hardly ever redeploy... but it is annoying while developing)..
I just generate the entities, type seam restart then "browse" the database, seam restart... browse...etc... then... It just seams to happen at random (but quite often). When I get an exception/debug screen, I can just hit F5, and it it will display correctly.
here is an example exception
