I'm currently trying FDT 4 for Flash/Flex development (was using Flash Builder) before, but I have a little annoyance.
I have two projects: GameCommon and GameWeb. GameCommon is a library, compiled to an SWC file, while GameWeb is a thin wrapper around that SWC and is compiled to an SWF (There's also a project GameDesktop which is an AIR wrapper around the SWC).
In Flash builder, the SWC would automatically get built when I edit and something in GameCommon, meaning that if I ran GameWeb afterwards, it would be updated.
In FDT however, I have to explicitly run a launcher to get it to build the SWC for GameCommon (after which it will automatically rebuild GameWeb). Is there a way to change this so it works more like Flash Builder?
