title: Unknown error in GWT
body: <p>I'm writing a module in GWT. It uses a WYSIWYG editor. It was running smoothly until I tried using RichText from GWT instead of WYSIWYG editor. Since it did not workout as expected, I rolled back to the old code (i.e. WYSIWYG). But now, when I run the compiled html file in a browser, I get an error </p>
  
  <p><code>Error: a is null Source File: http://www.xxxxx.com/sandbox/rss-manager/rss_manager/88DF3622F3340D0F082021E59419F325.cache.html
  Line: 1022</code></p>
  
  <p>It isn't showing any errors during compile time either. Its hard to figure out what the problem is. </p>
  
  <p>Please help</p>
