Vitali, this looks fairly straight forward... but now i'm having trouble wrapping this with a Composite so i can create my "clickable list" wiget. The issue is the HTML.wrap() which gives me an exception due to the element not being attached to the DOM ?... i'm missing something, but it's not apparent to me what it is and i'm having problems finding any solid examples in this list.
Would you be so kind as to provide a version of your code wrapped in a class that extends Composite ?
