It doesn't. Andy's approach is simplar to what I'm doing. I'm loading the wsdl on application creationComplete. I'll be moving it to the preloader when I get to customizing. For now, the wsdl load takes about a second to load in the background, so there's no apperant delay for the user. Hey, I'm the dense one. :)
