So can      we use the above interfaces and implement them to have classes that behave      according to our business needs? 2. Is there a limitation to what extent we can control JPDL actions, decision, tasks, events, and activities behavior ? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/533483#533483] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
