title: How to use EXT-GWT ComboBox
body: <p>How do I use ComboBox in <a href="http://extjs.com/products/gxt/" rel="nofollow noreferrer">EXT-GWT</a> with static data.
  For example I just want to hard code (for demo purposes) list of First Names and display it to the user.
  I don't want to use any dummy objects that they are using in their samples. Where can I find simple example with Strings?</p>
