Subject Re: Flex 5 in haxe

@Hordur
If we are all participating to this discussion on this mailing list, I
think it is because we all love Flex framework! :)
But we can't escape the pressure of customers coming to us with the
recurring question: Why Flex and not HTML5?
This question is easy to answer / to argument concerning desktop
applications (browser fragmentation, etc.), but concerning mobile
applications it is less obvious because there are other technologies that
can do almost the same, at least for "entreprise" oriented applications.
Concerning Adobe runtime dependency, if Adobe strategy was perfectly
aligned with Flex developpers strategy it would be OK, but unfortunately
Adobe took a different path lately, so we can't avoid asking ourself if
this dependency is not a threat for Apache Flex framework in a near /
mid-term future, at least for targeting mobile plateforms.
When I was speaking of Apache Flex to Apache Cordova bridge, I wasn't
thinking that it wouldn't be possible anymore to target Adobe Air runtime,
or to use Flash Builder debugging capabilities, I was thinking of the
possibility to "export" a Flex Mobile application to the HTML5/JS world via
Apache Cordova, for simple entreprise applications. You can still debug
with Air and just export your project when ready.
