That's one of the reasons all of our mxml classes have no constructor
arguments.
The code flow is then:
result = new clazz();
for (var p:String in args)
{
results[p] = args[p];
}

Subject: Re: [flexcoders] Re: Dynamic constructor invocation?
Hi again,
the solution I have so far is to make separate calls for each number of
arguments that needs to be passed to the constructor. It works, but of
course it is no elegant and generic solution.
case 1:
result = new clazz(args[0]);
break;
case 2:
result = new clazz(args[0], args[1]);
break;
etc.
regards,
Christophe
