In the function body, the This occurs when you try to use a removeChild with a display object that does not exist within the parent object you are trying to remove it from.

For example, in the following sample where myParent is a Sprite or some other DisplayObjectContainer instance that supposedly contains a child Sprite or some other DisplayObject called myChild :.

This could be because myChild was already removed prior to this call, or myChild exists within some other object. If this is happening when you think it shouldn't, try tracing the value of the child display object's parent to see if it's what you expect. To be safe, when removing a child display object from its container, you should make sure the object you're removing it from is, in fact, it's parent. This goes with the assumption that you need to explicitly remove that child from that specific parent.

If you just want to remove the child from the display list, you can explicitly reference it's own parent through its own parent property rather than an object reference for the object you suspect might be its parent. In doing so, you should check to see that parent exists. If it's null, it is already off of the display list. This is the standard approach for removing an object from the display list. Verify it's on the display list parent is not null then remove the object from it's parent directly.

There is one exception to this rule: event handlers for the Event. In this case, parent will be non-null but the removeChild will not work because the child display object is actually no longer on the display list. This circumstance would be extremely rare, but for absolute assurance that your code would continue without interference, you can attempt to handle the error in a try-catch block when attempting to remove the child display object with removeChild.

The root , stage , and loaderInfo properties of the DisplayObject class are unique in that their values are dictated by whether or not the DisplayObject is a child of the active display list. If the DisplayObject is not, these properties will each be null. They will not have valid values until the object made a child of the active display list through addChild or addChildAt. You can identify when this occurs using the Event. As is the case with the mySprite examples, the mySprite variable was declared, so it exists, but it was never defined with a valid Sprite value.

This can be common when creating new classes where you have correctly declared all of the necessary variable members but may have neglected to define them before they're being accessed. A timeline instance no longer exists. If you navigate to a frame within the timeline of a MovieClip that no longer has a timeline-placed object you're referencing in code, that object variable will be null.

You will need to make sure you're on the correct frame or at least check to see if the object variable is still valid when used. It is common for people to refer to TypeError: Error Cannot access a property or method of a null object reference as a runtime error bug.

When it comes to software like Adobe Flash Player, engineers can use a variety of tools to try to weed out these bugs as soon as possible. As with anything in life, sometimes problems like error get overlooked.
