title: Eclipse 3.5 is generating a "method not applicable for the arguments" error for no reason at all
body: <p>The error is this:</p>
  
  <blockquote>
    <p>The method add(String, int) in the type DataNode is not applicable for the arguments (String, String)</p>
  </blockquote>
  
  <p>However, in the DataNode class, I have a number of overloaded <code>add()</code> methods, including one that takes a <code>String</code> and an <code>int</code> and one that takes two <code>String</code>s. It appears that Eclipse isn't "seeing" the right <code>add()</code> method.</p>
  
  <p>I've tried things like refreshing the project and files and removing the method, saving the file, then adding it back. No matter what I've tried, the error persists.</p>
  
  <p>Does anyone know the cause and how to correct it?</p>
