Why doesn't my ActionScript 3.0 program work?

Question

ActionScript

Please explain what is the problem. The program uses fl.controls.ComboBox, FlashDevelop issues:

Error: Definition fl.controls:ComboBox could not be found.

Answer 1

Probably, in the program you connected the ComboBox library, if you believe the error, like:
fl.controls:ComboBox
and you need:
fl.controls.ComboBox
Well, that is, a dot was put instead of a colon.
Perhaps I'm wrong, and ActionScript3 gives an error with a colon, although you wrote everything correctly in the code, xs.
In this case, check that the ComboBox class is located exactly in the directory in which you specified in the imports. Since the error tells you that it cannot find it.
