Flex 4 support

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to instantiate the FlexTracker in a Flex 4 project using 
FlashBuilder 4 beta 2

What is the expected output? What do you see instead?
Expected: Nothing, but the tracker should be instanciated.
Actual: Runtime error, because Application.application is null

What version of the product are you using? On what operating system?
Version: 1.0.1.319 on Windows 7 

Please provide any additional information below.
Suggested solution:
Change signature of constructor in FlexTracker.as to:
        public function FlexTracker()
        {
            super();

            _tracker = new TrackerCache();

            /* note:
               to avoid to create a hard reference to 
Application.application
               we get the class by reflection
            */
            var appclass:Object = getDefinitionByName( 
"mx.core::Application" );
            if ( appclass.application != null )
            {
                _app = appclass.application;
            }
            /* Flex 4:
               Use of Appliction.application has been replaced 
by FlexGlobals.topLevelApplication
               this will make tracking in flex 4 possible
            */
            else
            {
                appclass = getDefinitionByName( 
"mx.core::FlexGlobals" );
                _app = appclass.topLevelApplication
            }

            _app.addEventListener( Event.ADDED_TO_STAGE, _factory );
        }

Patch included for easy adaptation :)

I was still getting an error finding: Application.

So i changed the code to something like this:

try
{
appclass = getDefinitionByName( "mx.core::Application" );
_app = appclass.application;
}
catch (e:Error)
{
appclass = getDefinitionByName( "mx.core::FlexGlobals" );
_app = appclass.topLevelApplication;                
}

I guess the right thing would be to check appclass!=null, not going for any 
properties...

Hi,

I'm sorry but the stats don't work with the Flex SDK 4.1.
How can I use this patch with your .swc file ???

Where is the problem?

The tracking works without any problems on a Flex SDK 4.5.1 project!

Checkout the current source!

I've checked out the current source, but what do I do next? I've moved the 
contents from the "src" folder to my project and could import it, but it gives 
me an error with the "log.as"

What do I have to do after checking out the current source? Could someone 
update the  "official .swc download"? Google is "officially" pointing to it but 
it doesn't the .swf doesn't work anymore.

Thanks in advance!

I also get issues regarding Log.as in a flex 4.5.1 project.
