I've currently started working with Flash CS 5.5 and I use Flash Builder 4.6 to work with AS3 files.
A problem arrised when I try to access an instance of a symbol placed on the stage or inside of another symbol. Flash Builder doesn't recognize the existance of said instance and shows this as an error. (The code compiles fine though.)
Is there any way of bringing instances placed using the Flash CS Editor to Flash Builder's attention? (I've also noticed that even the code editor of Flash CS doesn't recognize these instances.)
