Solved my problem and understood what was by this thread :) http://www.jboss.org/index.html?module=bb&op=viewtopic&t=129225 So i used a script to leave a node not a state. This is the part of my process, i'll need to send a mail instead to use the node specified. I will start now to see how mail nodes work :). | <state name="stateA"> | <timer duedate="5 seconds" name="MailSender" transition="to testMail"> | </timer> | <transition to="questionnaire_decision" name="to_questionnaire_decision"></transition> | <transition to="testMail" name="to testMail"></transition> | </state> | | <node name="testMail"> | <script> | executionContext.setVariable("pippo","pippo"); | executionContext.leaveNode(); | </script> | <transition to="stateA" name="backtoStateA"> </transition> | </node> | In the node i set a variable in the JBPM context, and from JBPM console i remove the variable and it is back after the 5 sec timer.
