Yahoo Astra flash component error BaseScrollPane not found

Question

I'm trying to use the Astra library from Yahoo but I'm getting an error saying the base class BaseScrollPane is not found. It appears to be imported from fl.containers.BaseScrollPane, which leads me to believe it should be a part of the base flash 10 library and therefore should be available, but it appears to be missing. Is this part of a separate package from somewhere?

Update: For what it's worth, I found the actual class files in the Configuration/Component Source folder on my hard drive, but adding that to the class path (as well as the Components directory) did no good. I ended up fixing the issue by dragging a scroll pane component to the stage from the Components window and then deleting it, but I'm not sure what exactly that action changed that made it work, and would like to know for future reference.

Answer 1

you saved me a bunch of time! thanks for taking the time to update your post!

Answer 2

The "fl." packages are not part of the Flash Player.

So in order to use components that depend on them, you need to ensure that the required classes are compiled into your swf.

Dragging the ScrollPane worked because it brought along with it into your FLA's library the same classes that you needed.
