Question : TypeError #1009 - Flash CS3/AS3

I have a runtime error in a Flash application. I have dealt with this error before, but I am unaware of the meaning of "at MethodInfo-313()". A similar error has also occurred with "at MethodInfo-323()". Please educate me! Thanks.

TypeError: Error #1009: Cannot access a property or method of a null object reference.
      at MethodInfo-313()

Answer : TypeError #1009 - Flash CS3/AS3

MethodInfo refers to an anonymous or nested function, hence why Flash can't give you a more specific identifier than number 313 or 323. If you can at all avoid writing functions in this way, it is advisable, not least for debugging!
