FlexBuilder 3 Linked folders not picking up as files.

Question

I am using Flex Builder 3 to write a flex component. I have created a real folder path \common. Under common I create a Linked Folder to Session.

Session points to a shared source folder with a item with a namespace of common\Session\ClassName.

When I go to compile the project FlexBuilder warns that it was unable to find the type.

if I stop using Linked folders and create a physical \common\Session\ in my project and place SessionInfo.as in the folder then it works.

just in case my textual explanation is a bit obscure here is the layout.

\src\common\Session\SessionInfo.as

namespace of SessionInfo is common.Session.

If you need any further info just let me know.
