Error #1009: null object reference

mrwizzer · August 18, 2009, 7:59pm

I think I’m getting close on this, but I keep getting the error message that reads:

"TypeError: Error #1009: Cannot access a property or method of a null object reference.
at com.realeyes.media::AS3videoPlayer() "

I have a feeling it’s likely in my constructor block, but I don’t know where else to put the addEventListeners there. (See below)

Any suggestions?

Thanks!
