title: JQuery UI Autocomplete, value after select (by mouse) is different than (by arrow-keys)
body: <p>I'm using <code>jQuery UI Autocomplete 1.8.1</code> with <code>Jquery 1.4.2</code> and I have this issue.</p>
  
  <p>At first, I can't force the value of the Autocomplete input field, well this is not a big problem.</p>
  
  <p>But I have this issue with it:  </p>
  
  <p>I doesn't act similarly when a user <code>select</code> a choice using mouse to using keyboard arrows. When using keyboard everything is fine and the value appears after select in the input text box, but when using mouse it sticks with the old (typed) value not the selected one.</p>
  
  <p>How to control this (textbox value after select)? and why there are different behaviours?</p>
  
  <p>P.S: changing the value of the input box inside the <code>select</code> function is useless since it can't be done!</p>
