Bug 340223

Description Rick Barkhouse 2011-03-16 15:00:44 EDT

When trying to create a JAXB Context using the class below:

public class Employee {
    @XmlID
    @XmlAttribute
    public Integer id;

    @XmlKey
    @XmlAttribute
    public String name;

    @XmlJoinNodes( {
            @XmlJoinNode(xmlPath = "manager/@id", referencedXmlPath = "@id"),
            @XmlJoinNode(xmlPath = "manager/@name", referencedXmlPath = "@name") })
    public Employee manager;

    @XmlJoinNodes( {
        @XmlJoinNode(xmlPath = "report/@id", referencedXmlPath = "@id"),
        @XmlJoinNode(xmlPath = "report/@name", referencedXmlPath = "@name") })
    public List<Employee> reports = new ArrayList<Employee>();
}

EclipseLink throws the following exception:

Exception Description: Property [manager] in class [documentation.Employee] has an XmlJoinNode declaration with referencedXmlPath [@id], but there is no XmlID or XmlKey property on the target class [documentation.Employee] with the XmlPath [@id].  It is required that there is an XmlID/XmlKey property with a matching XmlPath on the target class for each referencedXmlPath.

Adding a redundant @XmlPath annotation solves the problem but the user should not be forced to do this, because the XPath is implied by using @XmlAttribute.
