Daniel Kulp resolved CXF-3161.
------------------------------
Resolution: Not A Problem
Fix Version/s: Invalid
Assignee: Daniel Kulp
The JAXBElement<MetallicKleurType> kleur that is set into the BusType object
needs to have it's scope set so that the lookup within JAXB runtime can find
the correct kleur element handler. Ideally, use the
ObjectFactory.createBusTypeKleur method, but adding the BusType.class class to
the constructor would work.
In anycase, this isn't a CXF bug at all. At best, it could be logged with
JAXB to have them produce a better error message or handle scoping better.

> The following methods are included in the generated objectfactory:
> {code:title=ObjectFactory.java|borderStyle=solid}
> @XmlElementDecl(namespace = "http://test.nl/voertuigen";, name = "kleur")
> public JAXBElement<KleurType> createKleur(KleurType value)
> {
> return new JAXBElement<KleurType>(_Kleur_QNAME, KleurType.class, null,
> value);
> }
> @XmlElementDecl(namespace = "http://test.nl/voertuigen";, name = "kleur",
> scope = BusType.class)
> public JAXBElement<MetallicKleurType> createBusTypeKleur(MetallicKleurType
> value)
> {
> return new JAXBElement<MetallicKleurType>(_Kleur_QNAME,
> MetallicKleurType.class, BusType.class, value);
> }
> {code}
> Both methods have the same namespace and name, the createBusTypeKleur method
> also has a scope (in @XmlElementDecl). KleurType and MetallicKleurType are
> enums.
> When I marshall the BusType object with CXF, a nullpinterexception is thrown.
> The BusType class looks like this:
> {code:title=BusType.java|borderStyle=solid}
> @XmlAccessorType(XmlAccessType.FIELD)
> @XmlType(name = "busType", propOrder = {"kleur"})
> public class BusType
> {
> XmlElementRef(name = "kleur", namespace = "http://test.nl/voertuigen";,
> type = JAXBElement.class)
> protected JAXBElement<MetallicKleurType> kleur;
> public JAXBElement<MetallicKleurType> getKleur()
> {
> return kleur;
> }
> public void setKleur(JAXBElement<MetallicKleurType> value)
> {
> this.kleur = (value);
> }
> }
> {code}
> When the method createKleur in the ObjectFactory class has a scope too, or
> the names in the @XmlAccessorType are different, no exceptions will be thrown.
> I have attached the source code (as small Eclipse project).
