[flexcomponents] Flex 2.0 is it posibble to create global variable?

[elad_nyc]

I am trying to see if it is possible to create a global variable that 
will be avaliable throught the entire application. 

So far I had no success. I tried something like this:

var strGlobal:String = "Global";

But I keep getting: "It will not be visible outside of this package"

I am not sure if it is possible?! didn't the creators of flex thought 
of creating something "sessions" so the application can use variables 
globally?
