Problem with GetComponent

Hi guys,

Si I try to compile my project in Flash and it tells me this:

C:\Users\user\Desktop\SVN\Game2\Temp\StagingArea\Data\ConvertedDotNetCode\global\SSSCameraBase.as(31): col: 103 Warning: Migration issue: * is not a dynamic class. Instances cannot have members added to them dynamically.​

Is really weird becuase I looked and the code and it seems the next line is making the error:

Code (csharp):

1. GetComponent<AudioListener>().enabled = flag;
2.         camera.enabled = flag;

Would somebody know WHY this is happening? I mean is there's a bug in the GetComponent method for Flash or something???

Thanks!
