It means you're trying to manipulate an object represented by a variable with a
null value.
For instance,
var mc:MovieClip;
mc.x = 9;
will generate that error as you've just defined that mc will be a movieclip and
its initial value is null.
var mc:MovieClip = new MovieClip();
mc.x = 9;
Will not generate the error, nor will
var mc:MovieClip;
if (mc) { // check to see if mc is null before accessing it
mc.x = 9;
}

Subject: [Flashcoders] Keep getting "Error #1009: Cannot access a property or
method of a null object reference. at ProfilerAgent/allCompleteHandler()"
Hello,
I am currently trying to use the Flex Builder 3 Profiler only I am having
trouble with profiling this SWF I am having. The issue is that half the time I
am getting the following error:
TypeError: Error #1009: Cannot access a property or method of a null object
reference.
at
ProfilerAgent/allCompleteHandler()[C:\SVN\branches\3.2.0\modules\profiler3\as\ProfilerAgent.as:293]
Does anyone know how to get rid of this problem or this error basically mean?
An issue on my side which is causing this?
Thanks,
Weyert de Boer
