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).

These should be the steps required to make it work on 10.2. I need to re-verify or you can do so:

If there is not a 10.2 playerglobal.swc at "frameworks\libs\player\10.2" find one from another
SDK and put it there.

Base Dir

build.properties global.playerglobal.version = 10.2
build.xml search for 11.1 or 11.0 and replace with 10.2

/frameworks

air-config.xml <target-player>10.2</target-player>
<swf-version>11</swf-version>

build_framework.xml <property name="playerglobal.version" value="10.2"/>

flex-config.xml <target-player>10.2</target-player>
<swf-version>11</swf-version>

/frameworks/projects

For each non-mobile project, check the build.xml for 11.1 or 11.0 and replace with 10.2

For each non-mobile project, check the .actionScriptProperties path to the playerGlobal.swc and make sure it is pointing to the 10.2 directory. You can leave the airGlobal.swc alone.

Rebuild the SDK.

Sorry about the previous comment. Jira was so nice as to automatically create a new account with an email reply... oops.

Thanks for that. I'll reverify for you.

The existing patches I've supplied for the build scripts work along the same lines as above, including injecting the correct Flash Player version numbers into flex-config.xml. (I had missed air-config.xml but easily fixed). I have changed the build.xml script so that the flash player version only has to be defined once at the top level build.xml.

Just waiting on the code to be imported into trunk and I'll reissue a full patch for review.

Verified for flash player 10.2. SDK compiler and a representative Flex application passed all unit tests and was able to run. This is not a comprehensive test obviously but a good indication that running 4.6 on FP 10.2 is possible with no code changes.

Just out of interest the Flex 4.6 SDK doesn't compile for flash player 10.1. The following error occur:
[compc] /Users/justinmclean/Documents/Adobe Flash Builder 4.6/Apache Flex/frameworks/projects/framework/src/mx/managers/SystemManager.as(3561): col: 52 Error: Access of possibly undefined property softKeyboardRect through a reference with static type flash.display:Stage.
[compc] var softKeyboardRect:Rectangle = stage.softKeyboardRect;

There may be further errors beyond this one.

By the unit tests, I am assuming you mean the flex checkin tests presently?

As another aside the Flex 4.6 SDK does compile and works with the 11.2 beta player. The 11.2 beta playerglobal.swc is currently at a public URL here:
http://download.macromedia.com/pub/labs/flashplatformruntimes/flashplayer11-2/flashplayer11-2_p5_playerglobal_013112.swc
(From http://labs.adobe.com/downloads/flashplayer11-2.html)

Note that some of the build files use local.playerglobal.version or worse have hard coded versions.

Noticed and already corrected.

Patch for build_framework.xml

Flash player version and locale have been moved to a build.properties file (so that other build.xml scripts can use it).

Patch for all build.xml files. This has not been fully tested as we don't have a full checkin of all required bits to SVN. However it may still be useful.

Changes include:

• ability to set flash player version number and locale in a single file
• removed all hard corded references to flash player version and locale
• changed ant path to match current directory structure
• removed javascript target (not donated yet)

Please don't commit these changes until we finish getting all the Adobe code (at least modules and the top-level build files) in the repository. There are changes to some of these files that were patched and it will make it very difficult for me to finish committing the code if I have to worry about integrating these changes as well.

Would you be OK with the changes to build_framework.xml were checked in? When do you expect the modules and the top-level build files to be checked in?

Changes to build_framewok.xml have been checked into the patches branch. No changes to build.xml scripts have been checked in.

If you are checking the changes into a branch you can make changes to any of the files, including the build.xml files.
