[Seaside] Accessing the root component from a child one

[Esteban A. Maringolo]

Hi,

	It is possible to make a call from a child component to a parent 
component. I mean, from one child (a kind of pane), make the top 
(the main page) component call another component.

	Example:
	
WARootComp
  \-- Child 1
  \-- Child 2

	I want that when some action is performed at Child 2, it  make 
WARootComp call to other Component. I could have a link (i.e. 
instVar) from child to parent, but i want to know if there is a more 
seaside way of doing this, something like topComponent, root 
component, or alike. Ala topShell in standard views.

	Thanks in advance.
