I think most of us use the PropertySelection component instead of
select and option.
Then you would encode your values via an IPropertySelectionModel.
Cheers,

Why do you need to change that? Are you submitting to a tapestry form?

Re: Change value property in @Option
Posted by Steve Shucker <ss...@vmsinfo.com>.
You should look at the @PropertySelection component to render a select
dropdown complete with options. It takes a "model" attribute (interface
IPropertySelectionModel) which essentially wraps a collection/array of
options. For your case, you probably want the
BeanPropertySelectionModel or StringConvertedPropertySelectionModel. If
those don't suit your needs, you can easily write a custom model.
