clone() code at top

======= Currently reads ================

return new CustomPersonEvent(type, bubbles, cancelable, personValue, timeValue);

======= Should read ==================

return new CustomPersonEvent(type, bubbles, cancelable, person, timeChanged);


The erroneous property names, personValue and timeValue, are the parameter names from the constructor and are out of scope in the clone() method.

The snippet underneath: "myContent.swapElements( 0, 2 );" should be "myContent.swapElementsAt( 0, 2 );"

The return type of the compareFunction named sortFunction should be int and not Boolean.

e.g. sortFunction (a:Object, b:Object, fields:Array = null):int
