I'm using 5.0.10-SNAPSHOT. I'm not trying to access the attribute on a page, it's just a control attribute, and i must have it in some of my classes. For me, is simpler to declare it in a superclass and access it directly in the subclasses, since subclasses inherit the attributes from the superclass. But it's not so bad to use it via getters and setters.
