usage

This code is pretty generic for connecting via Flash Remoting MX to multiple components with multiple methods.
It generates an onmethodname() event - i.e. ongetNews().
For multiple parameters, it is currently implemented that you must provide an array, object, char-separated string or other in params and then split or parse in the web service.
Give it a try and let me know if you got any issues/questions.

Sample:
[code]

#include "NetServices.as"
#include "Connector.as"

function init () {
  var gateway = "http://www.mysite.com/flashservices/gateway";
  var conn = new Connector(gateway);
  // parameters must be formatted as expected by the method to be used
  var myparams = ["bob","john","paul","mary"];
  conn.ejecutar("path.cfcname","methodname",myparams);
  // an event will be generated when information is received
  // the event will be named after the methodname prefixing it with "on"
  conn.onmethodname = function (results) {
    // do something with the results
  }
}

init ();
