In order to cast a class object you will need to call registerClassAlias(...); and then type cast the object. You can do so as in the following: package { import flash.net.registerClassAlias; import mx.utils.ObjectUtil; public final class DeepCopy { public static function clone(instance:Object, alias:String, Type:Class) : * { registerClassAlias( alias, Type ); return Type(ObjectUtil.copy( instance )) ; } } } Keep in mind if the Class constructor takes any arguments this will not work as you will get a #1063 RTE: Argument count mismatch... You will need to create your own deserialization API to handle constructor arguments as cloning an object will create a new instance which matches that of the cloned instance thus calling new on the Class object. I will update the DeepCopy class to implement the above method. Yes, this will only deep copy a native object.

You can do so as in the following:

package {

import flash.net.registerClassAlias;
import mx.utils.ObjectUtil;

public final class DeepCopy {
public static function clone(instance:Object, alias:String, Type:Class) : * {
registerClassAlias( alias, Type );
return Type(ObjectUtil.copy( instance )) ;
}
}
}

I will update the DeepCopy class to implement the above method.

Any idea? I get
