[jboss-jira] [JBoss JIRA] Created: (JBSEAM-355) Constructor injection of component dependencies

[Christian Bauer (JIRA)]

Constructor injection of component dependencies
-----------------------------------------------

                 Key: JBSEAM-355
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-355
             Project: JBoss Seam
          Issue Type: Feature Request
            Reporter: Christian Bauer
            Priority: Minor


Take the registration example. The 'user' component is instantiated by Seam when JSF first looks for 'user' in a page. It is then put in the SESSION context (think CONVERSATION for other use cases of what I'm proposing). Seam uses the default constructor to instantiate the component. 

Now imagine that some attributes of User are immutable and that the only way to set their values is through a different constructor. Also imagine that these values are actually present when Seam instantiates the 'user' component, e.g. in the current CONVERSATION. I'd like to tell Seam to call my constructor and use EL to bind the arguments.

Without this feature, immutable properties need to have public setter methods that I call later in an action method to wire in the required attributes manually.
