                 Key: JBSEAM-3596
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3596
             Project: Seam
          Issue Type: Feature Request
          Components: Core
            Reporter: Dan Allen
            Priority: Minor
             Fix For: 2.1.0.GA


There are times when the UI needs a collection of SelectItem objects, yet the business logic does not need to be aware of this requirement. Thus, we have a similar situation as with JSF data models.

It would be helpful to have an annotation counterpart to @DataModel named @SelectItems that outjects a list or hash as a list of SelectItem objects. If the property's type is a list, the label is assumed to be the same as the value. If the property's type is a hash, the entry's key is the option value and the entry's value is the option label.

@SelectItems
List<String> options;

@SelectItems
Hash<String, String> options;

In the case of a list, we could allow a label to be defined using path notation in an annotation property named labelPath.

@SelectItems(labelPath = "name")
List<User> users;
