TileList Components when loaded externally from separate SWFs do not have separate data

Question

I have 2 SWFs, each containing a different tileList Component and an additional SWF that acts as the master swf for the other two. It seems as if, which ever tileList component i load first will always over write the properties of the second. I have tried including the tileList inside the master swf library, i also have tried using:

var separateDefinitions:LoaderContext = new LoaderContext();
separateDefinitions.applicationDomain = new ApplicationDomain();

again with no luck.

Anyone have any ideas? thanks so much.
