I agree... a change is still a change doesn't matter from where it
came :) The currently implementation uses the browser event to fire
the change... but it can be easily done overriding the setText()
method... but then I got a new problem... every time that a new
component based on the original one is built I have a new problem...
and have to extend the new class to use the correct behavior... and
even more... I have to explicitly tell the user to use my new
component... like instead of creating a TextBox with "new TextBox()"
you'll have to create with "new XXTextBox()" on any component....
