Web services d2010 soap错误元素不包含单个文本节点

我搜索以连接到Web服务，但当我调用该方法时，我获得了这个错误元素OutputObj不包含单个文本节点'

这是我在导入WSDL文件时创建的单元：

这是来自Web服务的XML响应：

   </soapenv:Body>
</soapenv:Envelope>

当我调用GetDispatcherBeanFalse、、HTTPRIO1、0.dispatcherSOAP_RequestMsg时，我获得了错误

在RIO的BeforeExecute上，我只是控制XML请求，就像使用SoapUI的XML请求一样

在RIO的后期执行中，我只是控制XML响应，就像使用SoapUI的XML响应一样

GetDispatcherBeanFalse，，HTTPRIO1，0.dispatcherSOAP_RequestMsg返回一个MessageDTO，该类在UNDispatcherBean单元中定义，但我认为Delphi没有正确解析对对象MessageDTO的XML响应

你知道这个错误吗？我必须在哪里查找原因

这是我第一个使用Web服务和SOAP的项目，我希望不要写estupid之类的东西
