                 Key: TAP5-1398
                 URL: https://issues.apache.org/jira/browse/TAP5-1398
             Project: Tapestry 5
          Issue Type: New Feature
          Components: tapestry-core
    Affects Versions: 5.3.0
            Reporter: Howard M. Lewis Ship
            Priority: Minor


I'd like to see a special base class that could be extended to easily provide server-side logic for editting a field.

My scenario is a drop down list for selecting a country which Ajax-updates a drop down list for a region within a country and a text field for the city name (with autocomplete).

City is represented as an entity is my schema; I'd like an easy way to extract the city.name property as the initial value of the field when rendered, and then have a way to turn the country/region/city name into a City entity when the form is submitted.

I've cobbled together a mechanism using mixins, but it is a bit awkward to use. This seems to cry out for a simple subclass of AbstractTextField, perhaps EditField<T>.
