I will have to think about this for v2.0 of my app. - Kelly

I hear you Kelly, It sounds like its too late in the game to refactor your application. But, the Cairngorm micro-architecture would work nicely for this. Components use delegate classes that call a single data service class. Instantiated components create an instance of the delegate, that has an asyncronous event listening mechanism that links to the instance of the component. This allows for multiple components to go about thier own business, without affecting each other. Just another .02. Good luck with your solution. -TH --- In flexcoders@yahoogroups.com, "Kelly Birr" <[EMAIL PROTECTED]> wrote: > > Tim, > > I agree that actually embedding the WSDL may not be a good idea but I am > still hoping to find a way to pre-load the WSDL for the service into a > string the first time the service is called and then directly insert that > into the service every time the component is instantiated. > > My application is a CRM system that works by creating and destroying "pages" > that are self contained.
