To avoid converter problems, I changed my parameter to type String (and removed the "converterId" from my param). But my problem remains: the parameter is not passed (I always have my dumb default value in it) whereas all the other params are actually passed (the one pointings in EntityHome). Did I miss something ? Do the EntityHome objects manage the parameters differently ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4088944#...
