Marco Piraccini [http://community.jboss.org/people/mpiraccini] created the discussion "Service Task with no interfaces" To view the discussion, visit: http://community.jboss.org/message/629594#629594 -------------------------------------------------------------- Hi guys, With JBPM 5.1, if I define a Service Task with no interfaces (it's legal in BPMN2) -for instance using the new BPMN2 eclipse editor- this is not accepted. Indeed, when I load the resource in the knowledge base, I see: java.lang.IllegalArgumentException: No interfaces found     at org.jbpm.bpmn2.xml.ServiceTaskHandler.handleNode(ServiceTaskHandler.java:51)     at org.jbpm.bpmn2.xml.TaskHandler.end(TaskHandler.java:188)     at org.drools.xml.ExtensibleXmlParser.endElement(ExtensibleXmlParser.java:414) That behaviour it's very simple to reproduce (and the ServiceTaskHandler code is very clear) so I suppose that it's not a bug. Anyway, in my opinion this is not correct. In JBPM/Drools, I can set which WorkItemHandler I want to use for each Task "type". So if I want to have serviceTasks that are based on other informations (and not the interface)  I cannot do that using a Service Task. Ok, I know that I can do that with the "generic" task, but I'd like to use a Service Task (It's the correct task from the modeling point-of-view). Why this behaviour has been implemented? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/629594#629594] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
