i 'm not doing nothing abnormal. i'm executing manually a processInstance, you know: | ProcessInstance pi = new ProcessInstance(PROCESS_DEFINITION); | Token t = pi.getRootToken(); | t.signal(); | t.signal(); | t.signal(); | ... | as you can see, nothing abnormal. the problem is that when ends the last signal(). this is the moment when the problem appears. seems like the problem was when seam try to persist the last task instance. i don't know what's happening View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4000618#...
