Hi Adam, It sounds like flex builder is not including your interface in the swc.
Go into your library's properties, select "Flex Library Build Path" on the left. On the right, select the "Classes" tab. Look through the tree and make sure that the checkbox for your interface is checked. If it's not, check it. Clean the project then rebuild it. Try rebuilding your application now, it should pick up the interface. You'll even see it in code hinting. it seems that flex builder, by default, will not automatically include interface into the flex builder build path the way it automagically includes classes. so you have to tell it to include your interface. If you're doing this with the command line, make sure the name of the interface is listed in the "classes" argument. If you're still stumped, add a "-link-report=/[somepath]/linkreport.xml" argument to the compiler args for your library project. it'll spit out an xml file that tells lists the classes that are linked into your lib. check that your interface is listed there as a "def". Good luck. /r http://www.searchcoders.com/flex/?interface+library Adam Pasztory wrote: > I have a library project that gets compiled into an SWC file, and includes > shared code for several Flex Apps I'm working on.
