So, I've been at it for hours now and I'm still unable to divine the dark sequence that will allow me to have a code-behind setup for my application. I'm using Flash Builder 4 and trying to create an AIR desktop application.
Here's what I've tried:
Start Flash Builder 4
Start a new Flex Project called "TtA", setting it to run for Desktop
First, fix the immediate error I have about a complaint about not being able to find my locale by going to the properties of the solution and changing the Flex Compiler options from "-locale en_CA" to "-locale en_US". (Good job on shipping something broken out of the box, guys!)
In the solution, create a new package called "components"
Create a new ActionScript class called "TtAClass" in the "components" folder, making it a descendant of "spark.components.WindowedApplication"
In my "(default package)" edit TtA.MXML to add 'xmlns:my="components.*"' and change the 's:WindowedApplication' to 'my:TtA'.
I'm left with the error "Adobe AIR application is missing the corresponding TtAClass-app.xml."
So, that leads me to believe the app code-behind file can't see the required -app file and it doesn't match what I originally called my app, so let's change it to "TtA.as".
That brings me to"Adobe AIR application is missing the corresponding TtA-app.xml.". Well, at least it's looking for the right one now. So, let's try moving TtA.as to the default package.
Well, now it says "Unable to locate specified base class 'TtA' for component class 'TtA'.", which is bizarre since it's right next to the file it *can* see. Also, conveniently it did fixup my MXML file so that it is importing the file in its new location. Specifically it added 'xmlns:local="*"' to my MXML file and changed the root element of my file.
So, at this point I'm in a dangerous state. If I do much more eventually the Flash Builder process flies off in to space consuming massive amounts of RAM and eventually halting my PC.
tl;dr - I can't figure out how to correctly create a code-behind file for my default MXML application. Can someone please help me?

We hear you. This has been fixed in the coming release.
Try this for code-behind:
1. Create a new AS class (say MyClass) extending from WindowedApplication.
2. Right click your project, choose properties, go to Flex Applications.
3. Select MyClass, hit remove.
4. Now change the root tag of your existing MXML file to <local:MyClass by adding a namespace xmlns:local="*"
That should work.
