<div class="jive-rendered-content"><p>Hi guys, </p><p>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. </p><p>Indeed, when I load the resource in the knowledge base, I see:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>java.lang.IllegalArgumentException: No interfaces found</p><p>    at org.jbpm.bpmn2.xml.ServiceTaskHandler.handleNode(ServiceTaskHandler.java:51)</p><p>    at org.jbpm.bpmn2.xml.TaskHandler.end(TaskHandler.java:188)</p><p>    at org.drools.xml.ExtensibleXmlParser.endElement(ExtensibleXmlParser.java:414)</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>That behaviour it's very simple to reproduce (and the ServiceTaskHandler code is very clear) so I suppose that it's not a bug.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Anyway, in my opinion this is not correct. In JBPM/Drools, I can set which WorkItemHandler I want to use for each Task "type". </p><p>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.</p><p>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). </p><p>Why this behaviour has been implemented?</p></div>
