title: IndexOutOfBoundsException after switching from myfaces to mojarra
body: <p>I was forced to switch from myfaces (2.1.7) to mojarra (2.1.7). After this I'm getting exceptions like this one below all over the place. </p>
  
  <p>I'm submitting a form, that gives me validation errors. This is correct so far. I submit the form again, that gives me validation errors. This is correct so far. Now I submit the form again and I get the IndexOutOfBoundsException.</p>
  
  <pre><code>javax.faces.FacesException: Unexpected error restoring state for component with id someForm:someField.  Cause: java.lang.IndexOutOfBoundsException: Index: 1, Size: 1.
