Try adding the deck to the rootpanel before you add the widget to it. I'm not saying this is definitely it, but as a general rule, I try to build up widgets as I nest them, from the outside in, adding them to the DOM as soon as possible.
The reason being that if it is not connected, then 100% of 0 is 0. Hence height = 0. The deckpanel (last time I looked) sizes the deck innards to 100%. The SimplePanel doesn't.
