Deploy it and you have an asynchronous auto complete box:
A problem with many of the samples in the book is that they're intertwined, sharing some of the same classes. I'm trying to separate them so that the samples can become small and self-contained. I haven't completely finished that with the above sample, but I've done enough to get it basically working, as far as I can tell. I want to take this specific sample and write a sequel to the new Introduction to the Google Web Toolkit Framework. The support that the IDE provides for GWT is really good. I've been impressed so far, anyway.
