Override @GeneratedValue annotation with AspectJ [message #532820]

Hi!

I'm generating an annotation to set a defined sequenceValue to an id field for an Entity in Postgres DDBB.

I've been looking in AspectJ documentation:

- http://www.eclipse.org/aspectj/doc/released/adk15notebook/an notations-decp.html#declare-precedence

to apply precende rules between aspects.

I've created a new aspect applying the precedence rules and adding annotations to fields:


privileged aspect Person_Company_generated_id {

    declare precedence: Person_Company_generated_id, Person_Roo_Entity;
  
    declare @field: * org.company.test.generated.id.sequence.domain.Person.id : @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="PersonSeq");
    
    declare @field: * org.company.test.generated.id.sequence.domain.Person.id : @SequenceGenerator(name="PersonSeq",sequenceName="PERSON_SEQ", allocationSize=500, initialValue=601);
}

The aspect generated Person_Roo_Entity defines the annotation in the id attribute:

     @id
     @GeneratedValue(strategy = GenerationType.AUTO)

This only works if I remove the @GeneratedValue annotation from Person_Roo_Entity.

These rules can't override the behaviour of the @GeneratedValue annotation with the attributes that I redefined.

What I'm doing wrong?How can I override the behaviour/definition of @GeneratedValue with Aspects? is the preference wrong defined? Exists another way to override a sequence to an identifier with aspects?

Scenario:
* JDK-1.5.0_07
* PostgreSQL 8.3.8
* AspectJ 1.6.9.BUILD-SNAPSHOT

Thanks for your time.

Regards...
