So if 1.0.0 animations fail to animate with 1.5.0 js, that means that it is impossible to include 1.0.0 and 1.5.0 animation on the same page?
As far as I know you can not use two edge.x.x.x.min.js files on the same page.
It's a pretty dangerous assumption that current runtimes will support previous project files by default. When we update a runtime, we generally change some fairly core things going on... you can, however, have both 1.0.0 and 1.5.0 animations on the same page. All you need to do is to get the preloader for both animations loaded into the same page, and it will load in the correct runtime by default.
I have tried loading both 1.0.0 and 1.5.0 runtimes on the same page before I posted the question here. And it usually fails. I say usually, because in some rare cases it kind of works, but not exactly as expected. Animations don't animate as they should or mouse events don't work as they should. Also JS console is swarming with warnings (even more than usually)
With all the above information on the table I can only assume that there comes to name clashes and polluting of "window" instance. Given the runtimes are obfuscated, debugging is practically impossible and even out of the scope of my problem solving here I think.
Of course I allow the possibility that I'm doing something wrong. So Elaine if you could provide me with a working example I would appreciate that and I would gladly explore it.
