To view the discussion, visit: https://community.jboss.org/message/791560#791560 -------------------------------------------------------------- Hi Everybody, I'm jBPM-newbie and i need some help. I have installed jbpm-5.4.0.Final using the full installer. After starting the eclipse (with ant start.demo)  I have created a new jBPM project and modelled a new Process using BPMN2 Modeler. After process validation i get the following error: "This type of node cannot have more than one incoming connection". I know that the same problem has been solved see https://issues.jboss.org/browse/JBPM-3586 https://issues.jboss.org/browse/JBPM-3586. But my question is: where to set the system property (-Djbpm.enable.multi.con=true)   concretely? I don't know how to do that Thanks in Advance for any answer. PS: I hope that I'm in the right dicussion forum to ask such question. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/791560#791560] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
