Re: DeckPanel causes Widget to disappear
Arrgh. I thought I was using DeckPanel yesterday and was using StackPanel. The easiest way to debug it will be using firebug. Check to see it's structue after loading - i.e. is the widget a child? Sorry about that! Joe On Mar 4, 8:30 pm, Robert J. Carr rjc...@gmail.com wrote: Hi Joe- What API are you looking at? I only see one DeckPanel.add() method: void add(Widget w) Adds the specified widget to the deck. I've checked both 1.5.2 and 1.5.3.

Re: DeckPanel causes Widget to disappear
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.
