    seam-gen : two attributes of same kind in an entity

    Pierre Raoul Novice

      Hello,

      I use seam-gen (seam 1.1.7.RC1) to generate list and home classes from entities with jpaconfiguration .

      One class, Contract, has two attributs, seller and purchaser, with the same type Party.

      The generated ContractHome class contains:

       @In(value = "#{partyHome.managedInstance}", required = false)
       Party seller;
       @In(value = "#{partyHome.managedInstance}", required = false)
       Party purchaser;
      
      


      So seller and purchaser use the same instance!

      Any idea to get two different instances?

      Regards
      Pierre
