>          URL: http://issues.apache.org/jira/browse/TAPESTRY-628
>      Project: Tapestry
>         Type: Improvement
>   Components: Framework
>     Versions: 4.0
>     Reporter: Leonardo Quijano Vincenzi
>     Priority: Minor
>  Attachments: BeanPropertySelectionModel.java.patch

> Sometimes it's useful to bind a list of JavaBeans to a PropertySelect, and have Tapestry display a property (labelProperty), and use another property as the selected value (valueProperty). That would allow us to include database lists (probably instantiated using Hibernate or some other ORM) directly on the page, as model for the SELECT.
>  A simple implementation would go like this:
> public class BeanPropertySelectionModel<E> implements IPropertySelectionModel { 
>    public BeanPropertySelectionModel(List<E> options, String labelProperty, String  valueProperty);
>  
>   public String getLabel(int index);
>  
>   public E getOption(int index); 
> }
