I'm having problems getting my actionscript projects to work using the latest build of Astella (AS-112.507), and the same problem with two different projects.
I have two pure actionscript projects, although in both cases there are [Binding]-meta tags (in one case they are in a third party lib), so I get error that mx.binding.BindingManager and PropertyChangeEvent cannot be found.
I've been trying to find if there is a specific swc for the bindingmanager but I cannot find it.
If I make it a flex project (if I don't check the pure actionscript checkbox), but it seems like there is a lot of extra stuff added just for those damn bindings to work(?).
Classes BindingManager and PropertyChangeEvent are defined in [Flex SDK]/framework/libs/framework.swc. You can add it as a usual 3rd party library at Dependencies tab of the build configuration.
