There is no generic way to do this. Normally your application is
divided into at least three components. A root component with contains
a menu component and a "content component". The menu component
"somehow" sets the "content component" (sometimes the menu is also
rendered by the root component)

root component
 - menu
 - content

Somehow the component containing the component that should change
needs to be notified.

If you have access to the root component you can also try this:

rootComponent call: rootComponent class new

But before you write code like this:

self parent parent parent parent content: Home new
