title: GWT Layout is puzzling
body: <p>I'm fighting to understand the weird behavior of GWT Layout Panels. I'm wondering how GWT translate Layout logic into javascript and html. sometimes we don't get the expected Layout . something under the cover is done by GWT compiler.
  the GWT documentation is not clear enough on how Layout is performed under the cover.
  is there some good books or tutorials that explains well the GWT Layout issues?</p>
  
  <p>thanks.</p>
