Subject [JIRA] Created: (CAY-670) Class enhancement needed for JPA entity callbacks
Date Wed, 27 Sep 2006 16:00:48 GMT
Class enhancement needed for JPA entity callbacks
-------------------------------------------------

         Key: CAY-670
         URL: http://issues.apache.org/cayenne/browse/CAY-670
     Project: Cayenne
        Type: Task

  Components: Cayenne JPA  
    Versions: 3.0    
    Reporter: Andrus Adamchik
     Fix For: 3.0


Entity callback inheritance implemented per CAY-669 can't address one JPA requirement (footnote
[22] on page 62 of the spec):

"Note that if a method overrides an inherited callback method but specifies a different lifecycle
event or is not a lifecycle callback 
method, the overridden method will be invoked."

"java.reflect.Method#invoke" behavior is polymorphic, so calling a super doesn't seem possible
via normal Java reflection... So a class enhancemen seems to be required to call "super" from
within the object. Is there any other way to do that?
