Change a state in main.mxml from a script in another mxml

Question

Hi,
i'm having some trouble with my application, let's say i have the main application file called MAIN.MXML
in wich i have set different States, and have different forms.
now i have a form called loginForm which contains the textInput item for Login and Password, i also have a link Need to Register
which onClick will change the state to show in the same panel a different form registerForm (with the relevant textInput items)
now the MAIN.MXML includes a custom component called <comp: NetworkManager /> which includes all the logic scripts and MXML
tags to create and manage an HTTPService request to a PHP Server.
when the user click on the Login button, this will call a function included in the main.as script (imported in MAIN.MXML) which
will call a function in the script within NetworkManager.MXML passing all the form data.
in NetworkManager.MXML the script will create an XML message, will send to the PHP Server and wait the response... if this comes
true the user is authenticated, otherwise is not.
so far so good, i get the message sent, the correct response back. Now i want to hide the form in MAIN.MXML and put something like
Welcome firstName lastName!! instead. But i don't know how to do it. If i try to access the states in MAIN.MXML from the NetworkManager.MXML
i'll get all sort of errors which i don't have it here with me.
I know this sounds like a newbie question, and it really is ... any taker?
your help is much appreciated.
thanks
T.

who is the caller of loginForm then? i've tried with Application.application.loginForm but i do get the same error though.
loginForm is contained in a Canvas item, is it the caller? or who else?
thanks
