Hi. with CSS class we need to insert and remove class without affect the rest of them. So I propose to introduce two methods:
appendClassName (className:String):Boolean; removeClassName (className:String):Boolean; This methods will be based on RegExp to see if the className is already in the String or not and return a boolean true if the className was inserted or false if it's not (so the class was already there). I will do this in UIBase, but checking the hierarchy, I think this is something very close to HTML so maybe className manipulation should be in Element class? I'll be working on this in the meanwhile and always we can refactor to other place -- Carlos Rovira http://about.me/carlosrovira
