Jeff,
I imported the path where my components are (for example import
com.avsa.src.testes.*). Doing this, I could pass the component (form1.mxml)
as a parameter using the ViewHelper:
//****ViewHelper method****
public function LoadComponent(component:Object) : Void{
view.mainViewStack.destroyAllChildren();
view.mainViewStack.createChild(component);
}
//***Change Tree function ****
function fnChangeTree(event){
contentViewHelper.LoadComponent(form1);
}
Doing this, I don't need to have a AS class containing a switch/case to pass
the component as a parameter.
Maybe this could help!!!

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.

Hello,
a simpler solution is to have a viewstack with you 15 views (may be any
container (vbox, hbox, vdividedbox, etc.)), that viewstack standing for
example on the right of your tree. 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)
