我无法将 camunda 地图元素作为 Input parameter.Could 的子元素，不明白为什么？

Question

代码旋转网：

                CamundaInputParameter camundaInputParameter2=createElement(camundaInputOutput, CamundaInputParameter.class);
            camundaInputParameter2.setCamundaName("headers");

            CamundaMap camundamap = createElement(camundaInputParameter2, CamundaMap.class);
            CamundaEntry camundaentry = createElement(camundamap, CamundaEntry.class);
            camundaentry.setCamundaKey("Accept");
            camundaentry.setTextContent("application/json");

好吧，我遇到了同样的问题。根据 Camunda 文档：https://docs.camunda.org/manual/7.6/reference/bpmn20/custom-extensions/extension-elements/#inputparameter map 元素在 inputParameter 的子元素列表中，因此它应该可以工作，但实际上没有。解决方法是：

    CamundaInputParameter headers = model.newInstance(CamundaInputParameter.class);
    headers.setCamundaName("headers");

    CamundaMap map = model.newInstance(CamundaMap.class);
    CamundaEntry entry = model.newInstance(CamundaEntry.class);
    entry.setCamundaKey("Content-Type");
    entry.setTextContent("application/json");
    map.addChildElement(entry);
    //headers.addChildElement(map); does not work
    headers.getDomElement().appendChild(map.getDomElement()); // works
