Error Events:

Raising Errors

Through an End Events of type Error

    <bpmn2:endEvent id="EmdEvemt_error1" name="Throw Error 1">
      <bpmn2:incoming>SequenceFlow_0plhz17</bpmn2:incoming>
      <bpmn2:errorEventDefinition />
    </bpmn2:endEvent>

Error Handling

• If there is a Boundary Event to catch, it will be invoked
• else if there a start Event to catch it will be invoked.
• else Default error handling will be processed.

Example of Boundary Event

<bpmn2:boundaryEvent id="BoundaryEvent_catchErrors" name="Error Catcher" attachedToRef="Task_1yw3plw">
  <bpmn2:outgoing>SequenceFlow_0t9u8g1</bpmn2:outgoing>
  <bpmn2:errorEventDefinition />
</bpmn2:boundaryEvent>

Example of Start Event

    <bpmn2:subProcess id="SubProcess_0hpeg3q" name="Event Process" triggeredByEvent="true">
      <bpmn2:sequenceFlow id="SequenceFlow_1l0v2kk" sourceRef="StartEvent_catchErrors" targetRef="Task_10xnxy7" />
      <bpmn2:startEvent id="StartEvent_catchErrors" name="Error Catcher for Process">
        <bpmn2:outgoing>SequenceFlow_1l0v2kk</bpmn2:outgoing>
        <bpmn2:errorEventDefinition />
      </bpmn2:startEvent>
