Kevin,
I can apply the patch attached by Robert. Any objections? (honestly I
haven't spent much time lately looking into XML serialization, so I
will only run our existing test suite to ensure it passes)

>> --------------------------------------------------------------------
>>
>> Key: CAY-763
>> URL: https://issues.apache.org/cayenne/browse/CAY-763
>> Project: Cayenne
>> Issue Type: Bug
>> Components: Cayenne Core Library
>> Affects Versions: 1.2 [STABLE], 2.0 [STABLE]
>> Environment: Any
>> Reporter: Robert Zeigler

>> When XMLDecoder deserializes objects using a mapping descriptor,
>> no objects are registered with a datacontext until after all
>> objects have been initialized. However, cayenne requires a non-
>> null datacontext to correctly handle relationships. Hence,
>> dataobjects using the default cayenne handling of relationships
>> (either to-one or to-many) will be unable to deserialize objects
>> from XML (due to null pointers).
>> In the case of a collection, the getXXX method will return null,
>> and the XMLMappingDescriptor fails to "sense" a collection.
>> In the case of a to-one relationship, a NPE exception is thrown
>> trying to set the child property of the parent object.
>> The simplest way to fix this would be to make XMLMappingDescriptor
>> DataContext-capable (ie: will register objects with a datacontext,
>> if one is provided, as the objects are created). I've done this in
>> a local copy of the code. I will attach a patch when I get a minute.
