I'm currently using Seam 1.2.1 GA + JBoss 4.0.5 JEMS + MyFaces 1.1.4 + Tomahawk 1.1.3. Once Seam 1.3 is release, I'll have to upgrade everything (Seam1.3+JBoss4.2+?). Since Seam 1.3 is mainly tested with JSF 1.2 Sun RI, using MyFaces 1.1.5 seems not a good choice anymore(I've seen people having problems with MyFaces1.1.5 using cvs build). However, Tomahawk 1.1.5 seems only works with MyFaces1.1.5. This makes our migration process very difficult. I know Seam team always recommend not using tomahawk but there are some un-replaceable features in tomahawk that no one else provide. Are there anyone having same problem as we do? how are you gonna solve this problem? should we use MyFaces1.1.5 or Sun JSF 1.2 if we wanna keep tomahawk?
