Re: GWT Update widget in DOM when logical contents changed

This should be a fairly straight forward question.  Ive been relentlessly googling trying to find an answer to this but surprisingly I have found nothing.

I add a widget to a LayoutPanel, which is subsequently rendered and attached to the DOM.  How do I take the same widget and update its contents and have those changes applied to the DOM?

Widgets in GWT aren't "rendered", the are DOM elements (wrapped into widget classes); so effects are generally directly visible ("cell widgets" are different, and will generally defer DOM updates to the end of the event loop; but still).

What kind of widget are you dealing with? What are you doing with it? How are you adding it to the LayoutPanel? (and how are you "rendering and attaching it to the DOM"?) In other words; can you show some code?
