jbpm - 在任何信号边界事件上获取 "Data Output has no Data Type"

Question

我在 Eclipse Luna 中使用 BPMN2 建模器 v1.1.3.201503101616，为 Jboss EAP 6.1 开发 JBPM 6.0.3。每当我向事件添加信号边界事件时，它都会被标记为错误“Data Output Signal_1_Output () has no Data Type”。错误的类型为“jBPM Process Problem”。

例如，这是我整理的一个简单工作流程:

这是该过程的生成源代码(标记了错误的行):

  <bpmn2:itemDefinition id="ItemDefinition_4" isCollection="false" structureRef="String"/>
  <bpmn2:signal id="SignalFoo" name="SignalFoo"/>
  <bpmn2:process id="defaultPackage.Scratch" tns:packageName="defaultPackage" name="Scratch" isExecutable="true" processType="Private">
    <bpmn2:property id="str" itemSubjectRef="ItemDefinition_4" name="str"/>
    <bpmn2:startEvent id="StartEvent_1" name="StartProcess">
      <bpmn2:outgoing>SequenceFlow_1</bpmn2:outgoing>
    </bpmn2:startEvent>
    <bpmn2:scriptTask id="ScriptTask_1" name="Script Task 1" scriptFormat="http://www.java.com/java">
      <bpmn2:incoming>SequenceFlow_1</bpmn2:incoming>
      <bpmn2:outgoing>SequenceFlow_2</bpmn2:outgoing>
      <bpmn2:script>System.out.println(&quot;Hello world!&quot;);</bpmn2:script>
    </bpmn2:scriptTask>
    <bpmn2:sequenceFlow id="SequenceFlow_1" tns:priority="1" sourceRef="StartEvent_1" targetRef="ScriptTask_1"/>
    <bpmn2:boundaryEvent id="BoundaryEvent_1" name="" attachedToRef="ScriptTask_1">
      <bpmn2:outgoing>SequenceFlow_3</bpmn2:outgoing>
      <bpmn2:dataOutput id="DataOutput_1" name="Signal_1_Output"/> <-- Error
      <bpmn2:dataOutputAssociation id="DataOutputAssociation_1">
        <bpmn2:sourceRef>DataOutput_1</bpmn2:sourceRef>
        <bpmn2:targetRef>str</bpmn2:targetRef>
      </bpmn2:dataOutputAssociation>
      <bpmn2:outputSet id="OutputSet_1" name="Output Set 1">
        <bpmn2:dataOutputRefs>DataOutput_1</bpmn2:dataOutputRefs>
      </bpmn2:outputSet>
      <bpmn2:signalEventDefinition id="SignalEventDefinition_1" signalRef="SignalFoo"/>
    </bpmn2:boundaryEvent>
    <bpmn2:endEvent id="EndEvent_1" name="End Event 1">
      <bpmn2:incoming>SequenceFlow_2</bpmn2:incoming>
    </bpmn2:endEvent>
    <bpmn2:sequenceFlow id="SequenceFlow_2" tns:priority="1" sourceRef="ScriptTask_1" targetRef="EndEvent_1"/>
    <bpmn2:scriptTask id="ScriptTask_2" name="Script Task 2" scriptFormat="http://www.java.com/java">
      <bpmn2:incoming>SequenceFlow_3</bpmn2:incoming>
      <bpmn2:outgoing>SequenceFlow_4</bpmn2:outgoing>
      <bpmn2:script>System.out.println(&quot;Goodbye, cruel world!&quot;);</bpmn2:script>
    </bpmn2:scriptTask>
    <bpmn2:sequenceFlow id="SequenceFlow_3" tns:priority="1" sourceRef="BoundaryEvent_1" targetRef="ScriptTask_2"/>
    <bpmn2:endEvent id="EndEvent_2" name="End Event 2">
      <bpmn2:incoming>SequenceFlow_4</bpmn2:incoming>
    </bpmn2:endEvent>
    <bpmn2:sequenceFlow id="SequenceFlow_4" tns:priority="1" sourceRef="ScriptTask_2" targetRef="EndEvent_2"/>
  </bpmn2:process>

尽管有错误，Jbpm 能够毫无怨言地运行流程，边界事件似乎也能正常工作。我无法在 Internet 上找到任何其他提及此特定错误的信息。我也在寻找调整 jBPM 流程验证器的方法，但我在 eclipse 首选项中找不到任何相关信息。

这是合法的错误吗？有人可以建议如何解决它吗？或者，有没有办法禁用此验证规则？

jBPM 没有指定数据类型的要求(对于边界事件和其他地方)。 Modeler 错误地将此标记为错误。您能否打开一个 Eclipse BPMN2 Modeler Bugzilla，以便我们可以修复此问题(如果尚未解决)？
