Re: [Flashcoders] Flash Platform roadmap released - time to start learning HTML 5 unless you make games.
Have you guys given Adobe edge a try? It's like Flash MX, without easily accessible fonts or drawing tools... My fear is that handwriting HTML will always be cleaner and more structured than using an IDE. Imagine building a robust web application with tons of animation in Edge... It just seems impossible, where as Flash made it easy.

But these days business culture has changed to be primarily about profit, to the point where you actually get Kudos for gloating about how much money you were able to stock pile this quarter, instead of what great products you created, or how many customers you satisfied. This is a sad state of affairs that affects more than just Adobe, though they seem to have slipped into that black hole of profit gloating just like so many other American corporations. And the CEOs probably get real social kudos for that money gloating at their cocktail parties. Personally, I'll stay focused on products and customers, and hope that's enough to help change the culture back. I'm pretty much at the bottom of the totem pole though.

Re: [Flashcoders] Flash Platform roadmap released - time to start learning HTML 5 unless you make games.
I only played with Edge briefly on vacation last summer. :) I think that fear about HTML is warranted in terms of the quality of code you'll end up with - but the same can be said for hand written PostScript vs. Illustrator generated PostScript. Personally, I'll be happen when I don't have to edit HTML by hand anymore. That day came for PostScript a generation ago, and with some luck and hard work, it'll come for HTML. Kevin N.

No rules, you're right, just having the controller manipulate data just seems
to go against the spirit of what MVC is all about. Controllers are usually
used as communication busses in my experience.

Re: [Flashcoders] MVC style Correction
Yeah I understand how different the flavors are now. I didnt invent the
triangular flow paradigm of my framework, I read it in a book.
Lots of books, lots of 'spirits'
In the end it's just another 3 letter acronym.
