[flexcoders] Flex 3 Builder and package imports

[Edison]

Hi,

  I currently have a flex 2 project with the following structure:

[project-name]/
  src/
    web/
      assets/
      css/
      img/
      javascript/
      WEB-INF/
        classes/
        flex/
        flex_classes/
          com/
            adobe/
              cairngorm/
                etc...
            proj/
              business/
              commands/
              etc...
        lib/

The main source folder is: src\web

I'm having trouble creating new ActionScript classes under the folder
src\web\WEB-INF\flex-classes\com\proj\*

I get the error message: "ActionScript package names must only contain
letters, numbers, \"_\", and \"$\"." and figured out its because its
residing in the WEB-INF folder (which contains a '-' in the name).
However, WEB-INF isn't part of the package structure as the package
declaration always starts from "com.proj..." for all the current
classes. This was originally a flex 2 project using Flex 2 Builder
without any problems.

Is this a known problem with Flex 3 Builder? Is there any way to
specify source files within the main source folder (the Flex Build
Path only allows for source files outside the main source folder)?

Thanks in advance.

Regards,
Edison
