Flex 4 Web Service Introspection For Dynamic WSDL Locations

Question

In Flex 3, introspecting a web service resulted in a constructor that allowed the location of the web service to change at runtime.  It appears that the Web Service introspection tool now only allows the single WSDL URI that was specified in the WS Wizard.  It this the case or am I just missing something?
Flex 3 introspected services would create a service class with the following constructor signatures:
private var service:MyWebService;
service= new MyWebService(null, wsdlLocation);  // With parameters
or you could use:
service = new MyWebService(); //with no parameters
In Flex 4, it appears that you can only use:
service = new MyWebService();
So if you don't know the web server location until runtime, am I going to need to manually override the instrospected/generated _super_MyWebService.as class in order to get back the ability to point to different servers at runtime?
Anyone know why this has changed, or what the "new" way the Flash Builder 4 web service introspection tool uses for dynamic servers?
Thanks a bunch!

Answer 1

In Flex 4, it appears that you can only use:
service = new MyWebService();
add
service.wsdl = "your wsdl";
However if you want this to work you have to remove the hardcoded wsdl from the
superclass otherwise it will not reset it,
