title: How to Fix "Mark Occurrences" in Eclipse?
body: <p>Eclipse is a great editor, and among it's many wonderful features one of my favorites is the Mark Occurrences feature.  However, I recently installed the Aptana plug-in, and in trying to configure it I somehow managed to break Mark Occurrences in my Eclipse installation.</p>
  
  <p>The feature still works somewhat, but instead of highlighting all occurrences of a given object, it now only highlights the occurrence where it is first created.  In other words, in:</p>
  
  <pre><code>1. Dog dog = new Dog();
  2. dog.bark();
  3. dog.bark();
  </code></pre>
  
  <p>Only the "dog" in line 1 would be highlighted, not the "dog" in 2 or 3.</p>
  
  <p>However, before I know I had things configured such that all three "dog" references would be highlighted by Eclipse.  Does anyone know what configuration option I changed to "break" the marking of occurrences like this?</p>
