Debugging GWT

Finally figured out this nifty little trick to help with debugging GWT apps. Since the only way to work with CSS issues is in FireBug, and GWT generates so many tables, and divs, and so forth, how can you easily map from the generated HTML back to your code?

Add styles everywhere! Name the styles similar (the same?) as the Java class, and you now know exactly which <div> corresponds to which Java class!
