Jaxb XMLDirectMapping-未提供转换值

docx4j（我的主机）通常与Sun/Oracle JAXB实现一起使用；下面感兴趣的类是使用XJC生成的

继之前的一期之后，我将继续尝试使用EclipseLink MOXy

对于特定的DOM文档，我现在得到：

这就是JAXBBinder.unmarshall。如果使用JAXBUnmarshaller.unmarshal，也会发生同样的情况：

[Exception [EclipseLink-25004] (Eclipse Persistence Services - 2.4.0.v20120529-r11529): org.eclipse.persistence.exceptions.XMLMarshalException

导致破损的XML文件可在和处找到

有什么建议吗？

注意：我是专家组的组长和成员

正在解组的XML文档实际上无效。如果

ns1:val

属性中的值被更改为与允许的枚举值匹配，则一切正常

XML文件

xml文档的第95行是这样的

<m:radPr>
    <m:degHide m:val="1" />

CTRadPr

public class CTRadPr  implements Child
{
    protected CTOnOff degHide;
    protected CTCtrlPr ctrlPr;
    ...
}

CTOnOff

@XmlType(name = "CT_OnOff")
public class CTOnOff  implements Child
{
    @XmlAttribute(namespace = "http://schemas.openxmlformats.org/officeDocument/2006/math")
    protected STOnOff val;

MOXy中存在一个与处理无效值相关的错误。MOXy应该做的是，当它发现无效值时，它应该向

ValidationEventHandler

报告一个错误。如果

ValidationEventHandler

处理该事件，则不会为相应的字段/属性设置值。当您在JAXB RI中尝试这一点时，您将看到对象模型中没有填充无效值

您可以使用以下错误跟踪我们在此问题上的进展：

更新

我们已经在EclipseLink 2.4.0流中进行了修复。您可以从以下位置下载夜间标签：

---

注意：通过修复，MOXy将报告无效属性值的验证事件，就像它报告无效元素值一样。这与JAXB-RI不同，JAXB-RI为无效元素而不是无效属性抛出验证事件。我相信RI的行为是一个bug。

谢谢Blaise，很抱歉您发现XML无效（Word发出的docx不符合他们的标准！）。我没有想过在发布之前检查这个（正如你所注意到的，国际扶轮没有在这个问题上犯错）。

@XmlType(name = "CT_OnOff")
public class CTOnOff  implements Child
{
    @XmlAttribute(namespace = "http://schemas.openxmlformats.org/officeDocument/2006/math")
    protected STOnOff val;
