Ok, I need some help on this one. I upgraded from Flash Builder 4 to Flash Builder 4.5 and have switched my project to the 4.5.1 sdk. I use an ant script to build my project, so I modified it to use the appropriate flexTasks.jar, mxmlc, etc...
Now, if I start out with a blank bin-debug folder, then build and run the app everything works fine. However, if I then make a code change and build (without deleting the bin-debug) then run the app I get a runtime error:
ReferenceError: Error #1065: Variable ... is not defined.
at flash.display::MovieClip/nextFrame()
at mx.managers::SystemManager/deferredNextFrame()[E:\dev\4.5.1\frameworks\projects\framework\src\mx\managers\SystemManager.as:284]
at mx.managers::SystemManager/preloader_preloaderDocFrameReadyHandler()[E:\dev\4.5.1\frameworks\projects\framework\src\mx\managers\SystemManager.as:2633]

at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()
Again, if I delete the bin-debug folder and compile again it runs with no problems.
The variable it complains about is always a Class variable that points to an image file used as an icon. The code I use to create the var:
[Embed(source="/assets/icons/close-32x32.png")]
public var closeIcon:Class;
The file exists, and I verified that when it gives that error the file is in the bin-debug/assets/icons folder and the src/assets/icons/ folder.
After the error is thrown, if I hit the continue button in Flash Builder it then throws the same error again on the next Class variable pointing to an image file.
Any ideas? The delete/recompile takes several minutes, so obviously this is driving me mad.
