in the last case an eval might take some work out of your hands.

The problem is not passing the arguments, but how many arguments pass.
I can't use a text file, there I could only store basic types, but not
complex properties nor objects. I think about a dirty solution:
public class ClassFactory{
public static function createInstance(className:String,
args:Array):Object
switch(args.length){
case 0:
var clazz:Class = getDefinitionByName(className) as
Class;
return new clazz()
break;
case 1:
var clazz:Class = getDefinitionByName(className) as
Class;
return new clazz(args[0])
break;
case 2:
var clazz:Class = getDefinitionByName(className) as
Class;
return new clazz(args[0],args[1])
break;
....
case N:
var clazz:Class = getDefinitionByName(className) as
Class;
return new clazz(args[0],args[1],......., args[N])
break;
default 0:
throw new Error("Too many args. Max is N")
break;
}
}
}
