title: Custom List Definition using Document LIbrary
body: <p>I have created a Custom List definition based on the Document Library list. My List definition appears under the Custom Lists group in "Create Page" but when I try to instantiate a new List based on the custom definition  by entering the Name and the definition and clicking Create-</p>
  
  <p>It displays the Error Page with error message <strong><em>"File Not Found."</em></strong></p>
  
  <p>Any ideas on what that file may be that the runtime is looking for.</p>
