I have a Flex project and I would like to run an AS file from a source path entry. Flash Builder doesn't let me do this by disabling the 'run application' and 'set as default application' options when I right click on the AS file. If I add the file to .actionScriptProperties (in <applications>) manually, then in Project Properties > Flex Applications it shows as MyApp.as (deleted) but I cannot run it.
So, how do I run an AS application from a source path entry?
This is currently a limitation in Flash Builder. Application files will only work correctly when in a project's main source folder.
