Add attribute to <s:selectItems> allowing arbitrary values to be used as form "value"'s
---------------------------------------------------------------------------------------
Key: JBSEAM-1801
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
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?
