I agree with Romain's solution. The way I chose to solve this problem was create all my views (forms, reports, etc) as custom mxml components, and instantiate these using myViewStack.createChild(). That way the component isn't instantiated until it is actually requested. The one gotcha to this approach is that there is no "eval" of custom component names at runtime (as the component must be compiled), so if you're passing a component name to your view stack, you must first get a reference to a compiled component, which I am doing via an AS class containing a switch/case statement based upon the app name strings I am passing from the tree component. Not as elegant as I wanted, but it does work, and work well.
There may be a more elegant solution, but this is what I came up with given my level of knowledge at the time. With a little bit of work with HistoryManager, you can get the app to flip through a user's instantiated views using the back/forward button of the browser.

Now when people select a leaf on your tree, simply change the viewstack index ! (ps: it has nothing to do with Cairngorm, this is a Flex design solution) Romain --- In [email protected], "Rafael M.
