[seam-issues] [JBoss JIRA] Updated: (SEAMFACES-57) Use InputElement<T> instead of @InputField for injection of form input

[Dan Allen (JIRA)]

     [ https://jira.jboss.org/browse/SEAMFACES-57?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dan Allen updated SEAMFACES-57:
-------------------------------

    Description: 
The idea for @InputField is nice, but having access to only the converted value of a field is limiting. We should switch to a wrapper type at the injection point to provide access to the id, clientId and component. The implementation could also leverage the narrowing bean facility in Weld Extensions to make the producer more strongly typed.

Proposal:

@Inject
private InputElement<String> firstName;

@Inject
private InputElement<String> lastName;

@Inject
private InputElement<Date> dateOfBirth;

InputElement<T>
   String id
   String clientId
   T value
   UIInput component

The input element thus allows much more flexibility in terms of what the developer can accomplish in the validation method. One of those is being able to assign a message to a particular input field.
