I maintain a Flash-based app comprised of a fairly large number of individual swfs. In a nutshell it flows from a login management branch to a menu generation branch and finally hundreds of different content movies at the bottom.
Eventually I'll be dragging everything to AS2 but that bottom layer is going to take quite awhile...in fact, it'll probably be better suited to wait long enough for player adoption and go straight to AS3. In the meantime i have a number to needs driving an attempt to get the Login & Menuing systems updated to AS2 asap.
I understand I can't blend as1 & as2 in the same movie but it seems like i should be able to count on using popups to segregate the clips enough to create a stable, blended app. So that the Menu (running under AS2) fires the AS1 Content clips into a seperate popup. The complication will be that the content clips expect some values to be found in the Global and specific layers space.
Again, I'm sure a workaround is feasible - & that i'm not the first to face this need. Looking for an overview and others' experiences.
