Matthew Lieder commented on JBSEAM-1801:

How would I override it on a per-element basis? It looks like I can only override it on a per-app basis...?

>                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1801
>             Project: JBoss Seam
>          Issue Type: Feature Request
>          Components: JSF
>    Affects Versions: 2.0.0.BETA1
>            Reporter: Matthew Lieder
>         Assigned To: Pete Muir
>             Fix For: 2.0.1.GA
> Say we have the following:
> <h:selectOneMenu value="#{curPerson.favoritePerson}">
>   <s:selectItems value="#{people}" var="person" label="#{person.fullName}" />
> </h:selectOneMenu>
> The problem is that when the form is submitted, the value of "person.toString()" is stored in curPerson.favoritePerson. In some situations that might be acceptable, but not if the class doesn't have a guaranteed unique toString implementation. In this specific example, person.SSN would be the wanted field.
> To solve this problem, I recommend adding an "index" attribute functioning like the "label" attribute, except that the evaluated value is used for the "value" attribute in the generated HTML (the value that is submitted by the form). Should be pretty easy, I'm guessing?
