Error 303 with packaging my AIR icon

Question

Hi guys & gals
this is a very simple task that has been giving me a curious amount of trouble and frustration for being so commonplace, and I would appreciate the help
This is a part of my application-app.xml file
    <icon>
        <image48x48>data/application/icons/MY_ICON.png</image48x48>
    </icon>
When I try to export a release build in flash builder, it gives me error 303 Error creating AIR File, Icon is missing from package
In the 3rd step of exporting, under AIR File Contents (Select the output files to include in the exported AIR file) I do not have any option to select the icon file.. is it supposed to appear here, and if so how? Because it is not even displaying my data folder in this screen, much less let me select a file
I also couldn't find anything under the build path for the project properties to include assets either. Just source files and swcs.
What am I doing wrong here, this is supposed to be a very simple task and so far I have dumped hours into this without avail
Thanks again!

iPhone application icons
You define the following icons for an iPhone application:
•A 29-by-29–pixel icon—Spotlight search results on the iPhone and iPod touch use this icon.
•A 48-by-48–pixel icon—Spotlight search results on the iPad use this icon.
•A 57-by-57–pixel icon—The iPhone and iPod touch home screens display this icon.
•A 72-by-72–pixel icon (optional)—The iPad home screen displays this icon.
•A 512-by-512–pixel icon—iTunes displays this icon. The 512-pixel PNG file is used only for testing development versions of your application When you submit the final application to the Apple App Store, you submit the 512 image separately, as a JPG file. It is not included in the IPA.
In Flash Professional CS5, add these icons in Icons tab of the the iPhone Settings dialog box. See “Setting iPhone application properties in Flash Professional CS5” on page 14.
You can also add the locations of the icons to the application descriptor file:
<icon>
<image29x29>icons/icon29.png</image29x29>
<image57x57>icons/icon57.png</image57x57>
<image72x72>icons/icon72.png</image72x72>
<image512x512>icons/icon512.png</image512x512>
</icon>
The iPhone adds a glare effect to the icon. You do not need to include it in your source image. To remove this default glare effect, add the following to the InfoAdditions element in the application descriptor file:
<InfoAdditions>
<![CDATA[
<key>UIPrerenderedIcon</key>
<true/>
]]>
</InfoAdditions>
