Hi All,
I'm using wicket for a project at work, and for the most part, I'm really

Dipu

for this, and should override the getDisplayValue method.

Perhaps I don't understand the intended usage here.
It seems like the type of thing I want to do must be fairly
common. Say I want to list US States by full name, but
persist the abbreviation (code) in my model. A map of
Strings in the front end (display, value) to a String in the
In my first post, I had a couple of issues, and I don't want to lose sightof the other, because it is actually a bigger problem.That is in the

Most things i see use it as this:
Person

getCountry()
setCounter();
}
Country
