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
