Hi,

I have a solution to my issue.  I don't know if its the right one in seam lore.  If you practice a different technique, can you share?

Say I run a vehicle rental and so database has the following jpa entities (pseudo code in use):

abstract Vehicle {
    make
    model
    vehicleIdentificationNumber

Car extends Vehicle
Truck extends Vehicle

I have a /vehicleList.xhtml which presents a clickable list, like in the tutorial, except my intention is: when the user clicks on a vehicle, the /car.xhtml or /truck.xhtml edit screen appears, not /vehicle.xhtml.

The problem I'm trying to solve, is what to put on for the value of the s:link tag's action parameter?

My solution is

<s:link ... action="#{vehicleHome.editConcrete}/>"

editConcreate is a method on my VehicleHome that would return either /truck.xhtml or /car.xhtml (based on return of getInstance.getClass(), for example).

It works, I'm happy.  Feels sloppy.

Thanks.
