[jboss-user] [JBoss Seam] - argument type mismatch exception after Seam 2 upgrade - help

[terryb]

Having upgraded seam 1.2.1GA project to Seam 2 and JBoss EAP 4.2; my project is now unusable. I can't seen to find out why I get the following error and where it comes from. On some pages it occurs when html form is submitted, and on some just when page is being displayed?

Seam 2.0GA + Facelets + Sun RI. I followed Seam2Migration instructions.
