Why are you using an HTMLPanel if you're not using it from your code?
(no ui:field; unless you're relying on rootContent.getWidget(0) to
retrieve it?)
<div class="FormsContent"> should work just as well with less runtime
overhead.

Any reason you're moving _contentPanel from the "FormsContent"
HTMLPanel to the "FormsBox" one? Why not having your UiBinder ui.xml
right as you want it to be?

Where are you expecting the <h2>my box!</h2> to go?
If your MyBox widget implements HasHTML, then it should work (UiBinder
will call setHTML with "<h2>my box!</h2>"), otherwise, it doesn't know
what to do.
