I'm using jBPM 5.4 with Drools 5.5.0 -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/798470#798470] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
