Gavin, After I spent a lot of time trying to make this works (changing examples, from 1.1.6, CVS, debugging Seam code and so on), I found the reason: The problem was that I was using the el-ri.jar which comes with ICEFaces 1.5.3 distribution. I change back to el-ri.jar from Seam distribution and all works fine. I don't know why this happen, it seems they are different implementations, even the size is different (IceFaces 97Kb, Seam 95Kb form el-ri.jar). Do you know something related this? Anyway, Thanks you for your help. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4018986#...
