parser.instantiate() unsuccessful on tab containers

[psbucky]

As demonstrated in this jsfiddle:

​http://jsfiddle.net/qaHCr/1/

...parser.instantiate() seems to fail for certain types of widgets--notably the tab container.

jsfiddle doesn't have 1.9 support yet, but I can vouch for the same behavior so far.

If the flaw is in my understanding of the difference between parse() and instantiate(), then I'm just as happy to be pointed to my error--though instantiate() DOES often work in just this way for many other widgets.

Sorry, but you're misunderstanding the contract of instantiate(). It just creates the specified widget, so in your example it will create the TabContainer but not the child ContentPanes. It won't call startup() either.
