• I know you asked this a year ago…

  Using the examples, spread around the documents:

  animation.removeEventListener("complete",this);
  

  This would crash my emulator.

  The code below works. (Read the bit after for a disclaimer)

  //table is a TableView... but can be anything.
  
  var animation = Titanium.UI.createAnimation();
  animation.top = 45;
  animation.duration = 500;
  table.animate(animation);
  
  animation.addEventListener("complete",function(){
      animation.removeEventListener("complete",function(){});
      search.focus();    
  });
  

  I cannot prove that the approach I have taken works as I dont know how to debug current "events in a listening state".

  Equally, if it turns out that, this approach works. How does one go about contributing to the documents?

  Github?

• I don't think remove event listener is required here.

  In the Kitchesink project. The sliding animation example has some code that might give you some insight.

  button2.addEventListener('click', function()
  {
      // use inline style
      win.animate({right:-320, duration:500}, function()
      {
          win.animate({right:0, left:-320, duration:500}, function()
          {
              win.animate({right:0, left:0, duration:500});
          });
      });
  });
  

• William, while its true that my example doesn't require removeEventListener(), there are a couple of problems with your suggestion:

  1) My code is more complicated, but does require removeEventListener, and similarly doesn't work.
  2) I used the code example above because it is what Appcelerator provided in their documentation and it is a good minimal example of the problem.

• Your answer here was the clearest on the forum. Your example was better than the one in the docs. Thanks and great work man.
