[jira] Aktualisiert: (JAXME-58) IDREF handling does not follow JAXB spec (5.8.2)/reference implementation

     [ http://issues.apache.org/jira/browse/JAXME-58?page=all ]

Jochen Wiedmann updated JAXME-58:
---------------------------------

    Attachment: idMap3.patch

To keep the discussion open, a modified version of your patch. The IDREF properties should now be objects indeed.

I am currently considering, how to resolve an objects ID while marshalling.

> JaxMe's implementation of IDREF differs from the JAXB specification and the RI, as JaxMe seems to only set/get the IDREF String itself, as opposed to the RI which sets/gets the actual object being referenced.  From the JAXB spec (section 5.8.2):
> "An element or attribute with a type of xs:IDREF refers to the element in the instance document that has an attribute with a type of xs:ID or derived from type xs:ID with the same value as the xs:IDREF value. Rather than expose the Java programmer to this XML Schema concept, the default binding of an xs:IDREF  component maps it to a Java property with a base type of java.lang.Object. The caller of the property setter method must be sure that its 
> parameter is identifiable. An object is considered identifiable if one of its properties is derived from an attribute that is or derives from type xs:ID. There is an expectation that all instances provided as values for properties? representing an xs:IDREF should have the Java property representing the xs:ID of the instances set before the content tree containing both the xs:ID and xs:IDREF is (1) globally validated or (2) marshalled. If a property representing an xs:IDREF is set with an object that does not have its xs:ID set, the NotIdentifiableEvent is reported by (1) validation or (2) marshalling."
