XMLMappingDescriptor chokes on decoding collections for
CayenneDataObjects.
Cause:
1) CayenneDataObject.readProperty returns null (instead of an empty
list) for collection properties when the ObjectContext of the
CayenneDataObject is null
2) XMLMappingDescriptor is using an instanceof operator to determine
whether a property is a collection or not.
I consider this more of a problem with the readProperty method of
CayenneDataObject than an issue with XMLMappingDescriptor. It would
be nice if readProperty returned an empty list for to-many
relationships, even when there's no data/object context.
Thoughts?
For now, I've skirted the issue by having all of my data objects
extend a custom superclass, overriding the readProperty, and using a
bit of reflection to return an empty ToManyList when the returned
value is supposed to be a collection but the ObjectContext is null.
It seems to work... but I'm not sure of the repercussions of doing
this...?
