Hi Matt, we use a similar system to look up values for business object by primary key from the database which is highly de-normalized. We use Hibernate and have developed a base-class which we can either extend for unusual cases or use passed table/pk name via tag attributes.
It works well and as Hibernate caches everything there is little impact on the database :). One trick is to return different values from the PK lookup such as names/addresses etc.. which are in user-configurable through our GUI. To do this we have default "long" "short" and "medium" formats available in the base class which can be interpreted based on the table being accessed. We did find that a generic lookup-converter is less useful (from a GUI developer perspective) as it tends to break the MVC model and lead to code changes in the JSP when the underlying data model changes so we now have created sub-classed converters for each table which is preferable. -- View this message in context: http://www.nabble.com/Use-of-Converters-t1608471.html#a4360735 Sent from the MyFaces - Users forum at Nabble.com.
