I'm fairly new the Seam and looking for some advice on achieving the following:

Some tables (entities) in my application contain data that must be associated with the user that created the record.

I got the part where the entities are annotated properly to describe the 1 to * relationship.

The question I have is which one of the two following approaches Seam veterans would recommend to use (or if neither are appropriate, what's the alternative).

Approach A would be to override the "persist" method in entityHome such as:

  | public class myEntityHome extends EntityHome<MyEntity>
  | {
  |     ...
  |     @In
  |     User user; // That's the entity with the user's data
  |     ...
  |     @Override
  |     public String persist() {
  |         this.getInstance().setSubmitter(user); // Recording who created this using the entity's setter
  |         return super.persist();
  |     }
  | }

Approach B would be to handle this in an "action" bean.
