Class EnumPropertySelectionModel

java.lang.Object
  org.trails.component.AbstractPropertySelectionModel
      org.trails.component.EnumPropertySelectionModel

All Implemented Interfaces:

org.apache.tapestry.form.IPropertySelectionModel

public class EnumPropertySelectionModel
extends AbstractPropertySelectionModel

Implementation of a property model that works off of native java enum types.

The main diference with Tapestry's EnumPropertySelectionModel is that "allowNone" and the property used to get the label values (labelProperty) are both configurable.

The enum label/values are all translated by calling the method indicated by "labelProperty" By default labelProperty = "toString()", so it may be a good idea to provide a toString() method in your Enums if the types aren't what you would prefer to display.
