In http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4096257#... alexsmirnov pointed to me that this is a know issue within seam. By the way, within jpdl pageflow xml, can I issue a "null" transition, i.e., to stay in the page? Remember, I have a decision in the jpdl, and if some condition is met, I need to stay within the page and give a "null" as outcome so ajax4jsf renders only the changed parts (a facesmessages).
