“Specifies whether the component is included in the layout of the parent container.
If true, the object is included in its parent container’s layout.
If false, the object is positioned by its parent container as per its layout rules,
but it is ignored for the purpose of computing the position of the next child.”

Couple of minutes back when I tried to deep copy my object its just returning me null.
when I tried to assign it for a object its working.
I gone through the implementation its simple and effective…
public static function copy(value:Object):Object
{
var buffer:ByteArray = new ByteArray();
buffer.writeObject(value);
buffer.position = 0;
var result:Object = buffer.readObject();
return result;
}
Then why its not working… reason is simple 
Copies the specified Object and returns a reference to the copy. The copy is made using a native serialization technique. Confused.
Use the [RemoteClass] metadata tag to register the class with Flex so that Flex preserves type information when a class instance is serialized by using Action Message Format (AMF).
We have two ways to add the type information to the class:
1 . using [RemoteClass]
2. registerClassAlias(“my.pkg.class”,class);
This will resolve the problem.
