Unable to find named traits while packaging app for iOS

Hi,

I have an App that I want to deploy on iOS.
I follow the instructions provided by this article.
http://blogs.adobe.com/airodynamics/2013/03/08/external-hosting-of-secondary-swfs-for-air-apps-on-ios/

I have the issue while doing this. Shortly, I have several external SWF's
let's call them: base.swf, first.swf, secocd.swf... The base.swf has no
dependencies and if I specify only it ADT builds the IPA. But first.swf and
second.swf depend on code present in base.swf. If I add them to ADT command
line I have "Unable to find named traits: game.gui::GUIControl" message from
ADT. The game.gui::GUIControl is the class that present in base.swf and used
in first.swf.

The article doesn't answer: Must the external SWF's be independent or they
can have the dependencies among them?

Please clear this up for me.

Regards,
Dmitry.
