I just tried jboss-seam-1.1.0.BETA2 (jems-installer-1.2.0.BETA3) with ICEfaces 1.5 in the booking application. After configuring in our servlets (web.xml) and D2DFaceletViewHandler (faces-config.xml) and removing ajax4jsf (removing .jar and tag references), register.seam was automatically ajax-enabled (incremental update upon validation errors). So, Greg and I can definitely proceed with our integration based on Seam 1.1. (Should we provide in-depth technical details here, or is that the topic for another forum?)
