I know this error as I came across it and the problem is that you duplicated the class somewhere and you need to fix that, however, since you didn't provide the full source code it is hard to determine where the duplication is at. Due to the fact you have so many lines that have produce this error, but usually it is at the top of your code that might be producing the error (line 68). Since this is just a drop down menu your are better of just placing it within the application itself instead of connecting it with module and so that is all I can really offer you since I don't know much on debugging errors in flex.

 

I recommend that you click this link which lists google results for this error and that you check them out and see if one of those site might provide you a solution.
