Description Matt MacIvor 2011-03-02 13:01:22 EST

Given a class with the following property:
    @XmlElementRef(name = "inObject", type = JAXBElement.class, required = false)
    protected JAXBElement<Object> inObject;

When marshalling, the xsi:type is omitted:
<ns0:echoAnyType xmlns:ns0="urn:test:types"><inObject>foo</inObject></ns0:echoAnyType>

The correct document should contain an xsi:type="xsd:string" attribute on the inObject element.

When unmarshalling, if the xsi:type attribute is present, and exception is thrown:
org.eclipse.persistence.exceptions.DescriptorException
Exception Description: Trying to set value
[javax.xml.bind.JAXBElement@787c16] for instance variable [inObject] of type
[javax.xml.bind.JAXBElement] in the object.  The specified object is not an
instance of the class or interface declaring the underlying field, or an
unwrapping conversion has failed.
