Class Inside MovieClip Giving Runtime Error

Question

Hey guys.
I'm trying to place an instance of a movieclip (instance
name: tehMovieClip) from the library within another movieclip
(instance name: parentMovieClip) on the stage. tehMovieClip, the
movieclip going inside another movieclip, belongs to a class called
CollisonDetection (linkage properties, class:CollisonDetection,
Base Class: flash.display.MovieClip). When I put tehMovieClip
inside parentMovieClip, I get this runtime error:
TypeError: Error #1009: Cannot access a property or method of
a null object reference.
If I just place tehMovieClip on the stage by itself, it works
fine but I need it to be inside parentMovieClip. So what should I
do?
Just for your information, CollisonDetection extends the
project's DocumentClass which extends MovieClip.
Thanks in advanced!

The movieclip in question (the one I am placing inside
another movieclip) is linked to a class.

If yes. Is the Class linked to the movieclip have a
Constructor method with parameters?
Well this is my current constructor:
public function CollisonDetection() {
playerRefFromCollisonDetection.x = 600;
Now that you've said that, I deleted that middle line and it
seemed to work

If Yes. you found the problem.
And solution will be to update the class' constructor to have
no parameters.
Thanks buddy, but what if I need to have statements inside
the constructor such as triggering methods/functions inside the
class?
