[jboss-user] [JBoss Seam] - Re: Avoiding the DRY Principle with beans

[bfo81]

Mh... template method pattern, very beautiful. I'm messing around with JSF frameworks and example codes for a while now, and I often wondered why no one did it like this before.

I'd like to add something. I believe you can implement the setObject()-method in the abstract class PersistenceBean, too, since it should be the same in alle inheriting classes.


BUT: What about casting? I mean when you access the employee, e.g.
<h:outputText value="#{employee.name}" />
then JSF accesses the getName() method of the employee object. But since this one is a java.lang.Object and not a Employee I fear that we might get a MethodNotFoundError. Or is the reflection mechanism in Java smart enough for this?
