Looking at your process it seems like there is not timer definition given:      <boundaryEvent id="boundaryEvent_1" name="Boundary event" attachedToRef="userTask_1">       <outgoing>sequenceFlow_4</outgoing>       <timerEventDefinition id="timerEventDefinition_1"/>     </boundaryEvent> and it should look like this:     <boundaryEvent id="_4" name="TimerEvent" attachedToRef="_2" >       <timerEventDefinition>         <timeCycle xsi:type="tFormalExpression">500ms</timeCycle>       </timerEventDefinition>     </boundaryEvent> once you'll fix the process definition you'll be able to execute boundary events on a task.
