Subject Re: How to prepare Apache Flex 5 to run in the new AVM in Flashplayer 12?
Date Thu, 15 Nov 2012 21:25:59 GMT
Again it brings me back to the old thread "what is the essence of flex"
  What is it for you?

For me it's a framework for RIA, with descriptive language for UI, 
giving the possibility to have one code base and many platform targets.
And flex 1 was that.
but to be an efficient developement framework it had to be ported to an 
OOP language. and to be multi platform it was ported to desktop and to 
mobile devices with AIR. But it was only enhancements not a change of 
the essence of it. Thats why it was still named flex.
It could even be written in javascript and using phoneGap for multi 
platform, it would still be flex, even if it would be a far less 
efficient framework.

"Otherwise it was a complete mess"
When i read how Alex is talking about flex 4 architecture it seems to 
still be the case. And thats why we are talking about a complete rewrite 
from scratch.

Its interresting to read again the presentation of Apache flex on the 
The first part is exactly what i'm thinking about flex and could be the 
answer about the essence of flex:
"Apache Flex® is a highly productive, open source application framework 
for building and maintaining expressive web applications that deploy 
consistently on all major browsers, desktops and devices (including 
smartphones, tablets and tv)."

The second part is more details about the current version of flex and 
what you can expect of it right now:
"It provides a modern, standards-based language and programming model 
that supports common design patterns suitable for developers from many 
backgrounds. Flex applications can be deployed to the ubiquitous Adobe® 
Flash® Player in the browser, Adobe® AIR^(TM) on desktop and mobile or 
to native Android^(TM), IOS^(TM), QNX®, Windows® or Mac® applications."

Its interesting to see that it does not say that its AS3 !
and i think we will all agree that the Adobe's runtime dependency is not 
or should not be part of the essence of flex.
