Description Remy Suen CLA 2010-07-06 18:44:01 EDT 
1. Launch your inner.
2. Put a breakpoint in StackRenderer's showTab(MUIElement) method.
3. Show a view that's not in any of the existing stacks.
4. The breakpoint is hit twice.

The problem is because of LazyStackRenderer's 'lazyLoader' EventHandler instance.

As there is a PerspectiveStackRenderer and a StackRenderer, both of these instances are hooked to the event broker and two notifications get fired.
