Thanks for the input. It is what i was looking for. However, it is strange that there is no direct support for this... I was wondering if using one big top level conversation then nested conversations couldn't do the job (i am a noob, remember :) ? In fact, my problem is to manage workspace a la eclipse (http://jboss.com/index.html?module=bb&op=viewtopic&t=130054). If someone from the Seam team may answer to that question, it will be a real help! Thanks anyway View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4129577#...
