Justin Mclean commented on FLEX-14:
-----------------------------------
At a first pass looks like there's there's no SDK code changes required to use
the Flex 4.6 SDK in FP 11.0 or 10.3. The SDK compiles without errors for FP11.0
and FP 10.3.
I took an existing large application that uses a mix of mx and spark UI
components (using SDK 4.5) and recompiled it to use Apache Flex SDK 4.6 for
Flash Player 10.3 (from the white board area). There was a minor issue with the
version of the flex unit libraries. The version of the compiled swf was checked
with swfdump.
All unit tests passed and the application runs correctly in Flash Player 10.3.
There may be (or not be) an issue with using new FP 4.6 features or some
components the the application doesn't use. Even without further work I think
this provides a easier upgrade path to Adobe Flex 4.6 SDK (and the next build
of Apache Flex) for applications currently using older versions of the Flash
Player (11.0,10.3).
> Flex SDK 4.6 dosn't work on FlashPlayer 10.3 and requires FlashPlayer 11.1

> Issue Type: Improvement
> Reporter: Justin Mclean
> Assignee: Michael Labriola
> Priority: Minor
>
> Flex SDK 4.6 require a minimum FlashPlayer version of 11.1.
> From a quick look this is related to the new spark validator classes
> (spark.validators.*) using FlashPlayer 11 globalisation classes
> (flash.globalization.*).
> In particular enterprises can be slow to update Flash Player versions and
> this would enable a smoother upgrade path to people currently on 4.5 SDK (in
> a Flash player 10.3 environment) to the new Apache Flex 4.x SDK.
