title: Passing FromControl in a lookup override method
body: <p>I need to update a form in AX to use a complex drop down box.  To do this, I need to override the Lookup method.  According to the code example I have, code like this should work:</p>
  
  <pre><code>public void lookup(FormControl _formControl){}
  </code></pre>
  
  <p>Unfortunately, I receive the compile error "The method override has an incorrect number of parameters."  From what I can tell, this error makes no sense as this is a valid override of the method.  How do I fix this?</p>
