    Service Task with no interfaces

    Marco Piraccini Newbie

      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?
