Ah, the "is" issue. We don't seem to be able to get out from under a 'helper' method (or whatever the term-du-jour is for that thing) and a 'storage' property.
Personally I like to go from this AS: if (child is IChrome) to this JS: if (child.is(IChrome)) That would make it relatively easy to work with it in the cross compiler. Another possibility is to have a global function, but I don't like that very much. Thoughts? EdB On Mon, Jul 29, 2013 at 4:23 PM, Alex Harui <aha...@adobe.com> wrote: > Thanks for that.
