This doesn't reproduce for me. Can you check the library path of the project, and make sure it looks good?
- Problems view: any error messages? - Project > Properties - Build Paths page - Compile tab; make sure there are no error messages displayed at the top - Library Path tab - Make sure the icon for the SDK doesn't have a little red "x" over it. - Expand that node; make sure framework.swc etc. are in there Thanks - Mike Morearty, Adobe Flex Builder team --- In [email protected], "marcel.panse" <[EMAIL PROTECTED]> wrote: > > I have a Library project with some mxml file in there.
