Well I am using (until now ;)) interfaces for kind of this. > So, that is the reason for UIcomponent is an abstract class? > Actually, that was done for a different reason. Consider what would have happened if we had just defined UIComponent (an interface) but not UIComponentBase (an abstract class). Now, assume that JSF 1.2 wanted to add some additional methods to UIComponent. This would break every single third party component in the world -- not a good thing. That's why nearly all of the APIs in JavaServer Faces are abstract classes rather than interfaces. > > is the motivation for this? > > I was reading the source, so I *easily* changed ;) > > ok, I closed it :-) -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
