title: "No Suggestions" in NetBeans
body: <p>For a few days now I'm using NetBeans 6.8 for doing PHP work. 
  But even if a class-file is included and the methods are public and there's phpDoc used, NetBeans everytime shows "No Suggestions" in the window.</p>
  
  <p>E.g. I type</p>
  
  <pre><code>$user-&gt;
  </code></pre>
  
  <p>and press CTRL+Space, I do expect all the methods and variables but there aren't shown any. ideas?</p>
