[flexcoders] What's the difference in the way you add arguments to a webservice?

[Brian Holmes]

I create my webservices and operations on the fly and I've come across
these two ways of adding arguments to a server call.
 
 
when I create the operation, i can add arguments
 
        var op:mx.rpc.AbstractOperation = this.service[method];
             op.arguments = arguments;
 
 
or when I actually send the arguments I can add arguments
 
        var token:AsyncToken = op.send(arguments);
             token.eventName = method;
 
Either way,  it seems if I want to pass any sort of optional arguments
everything blows up. I was wondering what other people are doing
to pass optional arguments to a webservice?
 
thanks,
Brian.
