java - 我无法将 camunda map 元素作为输入参数的子元素。无法理解为什么？

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");

嗯，我也面临着同样的问题。根据 Camunda 文档:https://docs.camunda.org/manual/7.6/reference/bpmn20/custom-extensions/extension-elements/#inputparametermap 元素位于 inputParameter 的子元素列表中，因此它应该可以工作，但事实并非如此。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
