More Expression Language

In JSF, you use a simple EL to bind to the information you want to present and/or modify. For example, use #{UserList.selectedUsers} to reference a set of selected users, #{} to reference a particular user’s name, or #{user.role == 'manager'} to evaluate whether a user is a manager or not. At run time, a generic expression evaluator returns the List, String, and Boolean value of these respective expressions, automating access to the individual objects and their properties without requiring code.
