title: MvxAutoCompleteTextView stuck at 'Wait starting for '
body: <p>I try to use the MvxAutoCompleteTextView but it's stuck with the following output in Debug : </p>
  
  <blockquote>
    <p>mvx:Diagnostic:  3,57 Wait starting for </p>
  </blockquote>
  
  <p>As soon as I launch my application in the emulator (Android 4.3, Hardware keyboard DISABLED), I see the <code>Wait starting for</code> message and as I type, no suggestion is shown.</p>
  
  <p>My ViewModel :</p>
  
  <pre><code>public class FirstViewModel : MvxViewModel
  {
    public FirstViewModel()
    {
      ClearResults();
    }
  
    public string[] AutoCompleteSuggestions { get; set; }
  
    private string _currentTextHint;
    public string CurrentTextHint 
    {
      get { return _currentTextHint; }
      set 
      {
        _currentTextHint = value;
        base.RaisePropertyChanged(() =&gt; CurrentTextHint);
        if (CurrentTextHint == null || CurrentTextHint.Length &lt; 3)
          ClearResults();
        else
          BeginSearchAsync();
      }
    }
  
    private void ClearResults()
    {
      AutoCompleteSuggestions = new string[0];
      base.RaisePropertyChanged(() =&gt; AutoCompleteSuggestions);
