Description Chris Delahunt CLA 2008-03-28 14:36:07 EDT 
EclipseLink supports basicIndirection which requires objects use a ValueHolderInterface attribute type which needs to be supported in orm.xml.
Comment 1 Doug Clarke CLA 2008-03-31 09:26:07 EDT 
The eclipselink-orm.xml must allow developers the ability to select our various indirection policies. When using annotations EclispeLink will default based on the type used in the class when a relationship is specified as LAZY.

This does mean that we should support the direct usage of ValueHolderInterface in a domain model with annotations but its usage should be quite rare and definitely a lower priority.

As for the XML we should have support for defining the indirection policy in all relationship mappings.

	<indirection-policy>Basic</indirection-policy>

This will allow a enum set of values as well as an option for a user to provide a fully qualified class name where the class implements IndirectionPolicy.
Comment 2 Doug Clarke CLA 2008-04-15 15:49:29 EDT 
For models where ValueHolderInterface is used we should address processing to ensure it works with the weaver.

	@ManyToOne(fetch=FetchType.LAZY, targetEntity=Employee.class)
	private ValueHolderInterface manager;

We will defer support for proxy-indirection from the 1.0 release
Comment 3 Peter Krogh CLA 2009-04-03 16:02:29 EDT 
These JPA enhancements were accidentally assigned to 1.1.1.
Comment 4 Doug Clarke CLA 2009-11-27 11:00:14 EST 
Moving to 2.1 where our goal is to have the eclipselink-orm.xsd fully support all native features currently available in the deployment XML XSD
Comment 5 Guy Pelletier CLA 2009-12-08 09:07:55 EST 
Updating priority due to revised bug categorization process.  See the following
