I tried adding reusable flex 4 component to a library project and use those in projects i have. One issue that i'm banging my head against the wall to try to fix right now is the fact that the swc doesn't contain any of the mxml skin files that are part of the components. only the AS files are part of it.
Any idea what could be doing that ?
Verify your build path settings in project properties > Flex Library Build Path > Classes.
