I have a Flash application which loads in external .swf files for drawing
charts. My main .swf is compiled for the Flash 7 player, while the loaded .swf
files are compiled for the Flash 6 player. The Flash 6 .swf is not able to
access variables or functions which are defined in the _global context of the
Flash 7 .swf file. But if I have two Flash 7 movies, or two Flash 6 movies,
things work fine.
Is there some known interaction I should know about? Specifically, shouldn't
two .swf files compiled for different versions player still share the same
_global scope?
As an example, I've created flash6.fla and flash7.fla. They have the following
action script:
---flash7.fla---
_global.callbackFunction = function() { trace("Got Callback"); }
loader_mc = _root.createEmptyMovieClip("loader_mc", 3);
loader_mc.loadMovie("flash6.swf");
---flash6.fla---
trace("Loaded Flash6.swf");
trace("_global.callbackFunction: " + _global.callbackFunction);
---------------
The trace function shows me that _global.callbackFunction is defined if
flash6.fla is published for Flash 7 players. But if I republish, targeting the
Flash 6 player, the function is longer defined. It is like they have totally
separate _global scopes. If I switch from _global to _root, however, things
work fine. So, I can work around the issue. But it strikes me as real odd that
the two .swf files don't share the same _global variable space.
Clues?
