Using DataFactory to create a generic data object
-------------------------------------------------
Key: TUSCANY-1074
URL: https://issues.apache.org/jira/browse/TUSCANY-1074
Project: Tuscany
Issue Type: Task
Components: Java SDO Implementation
Affects Versions: Java-SDO-Mx
Reporter: Kelvin Goodson
Priority: Minor
Before the last regeneration of ModelPackageImpl there was a use case which was
supported that permitted a call to
DataFactory.INSTANCE.create("commonj.sdo","DataObject"); which resulted in the
creation of an instance of AnyTypeDataObject in the namespace
"http://www.apache.org/tuscany/2005/SDO";. This was a manual fix up to the
generated ModelFactoryImpl class which didn't get transferred to the new
version.
TUSCANY-1055 drew our attention to this, because it blocks the creation of
abstract types, such as "commonj.sdo","DataObject", which is the correct thing
to do according to the spec. This task is to attempt to rediscover the use
case that required this behaviour and rethink how to support it. A possibility
is to introduce into the SDO spec the concept of a concrete type of
"commonj.sdo","GenericDataObject", which would be open and mixed etc.
