I don't seem to be able to dock a toolbar to the top and bottom of a panel. The bottom toolbar does not show up. Are there any specific requirements for this configuration?

I'm using a Container with a card layout that contains all my views. This container is added to the viewport and has fullscreen to true. My subviews have no layout specified.

Like this:
-viewport
---Main (extends Ext.Container, cardlayout, fullscreen = true)
-----List (extends Ext.List)
-----Detail (extends Ext.Panel)
-----Add (extends Ext.form.Panel)

I am currently using 'docked' instead of 'dock'. I tried both but I'm unsure which one is correct. Using PR2.
