[jira] [Created] (MYFACES-3319) Make create AjaxBehavior accessible in AjaxHandler

Make create AjaxBehavior accessible in AjaxHandler
--------------------------------------------------

                 Key: MYFACES-3319
                 URL: https://issues.apache.org/jira/browse/MYFACES-3319
             Project: MyFaces Core
          Issue Type: Improvement
          Components: JSR-314
    Affects Versions: 2.1.3
            Reporter: Michael Kurz
            Priority: Minor


I'm currently trying to create a custom ajax tag that is based on f:ajax but supports an additional attribute. For this, I wanted to create a new tag handler that extends AjaxHandler.

What I found out is, that it is VERY hard to do so. The creation of the AjaxBehavior is buried inside applyAttachedObject(). The only reasonable way I found to set an additional value expression on the created AjaxBehavior is to pass in a wrapped FacesContext/Application from the derived class.

It would be so much easier, if, for instance, creating the behavior would be done in a protected method. Then the behavior would be accessible in derived classes.
