[flexcoders] Imported skin built using Flash doesn't work well with scale-9 and bitmaps

[João]

Hey guys,

is this a bug or a missing feature?

I have created a skin of a button on Flash CS3 using the Flex Skin
Design Extensions. After importing the skin to Flex using the import
artwork, the scale-9 grid doesn't work well if my button was skinned
using bitmaps. 

-Is this supposed to happen?
-Is there a workaround?
-Should I fill this as a bug or wanted feature on the Adobe JIRA?

Thanks,
