title: Two-way data binding for array collection in flex
body: <p>I am using flex 3.5 sdk. I want to bind an array collection to a form. The structure of array collection is like this.</p>
  
  <pre><code>MyClass :
  var value : String;
  var arr : ArrayCollection;
  
  Each element in arr above is an object of MySecondClass
  
  MySecondClass :
  var val1 : String;
  var val2 : String;
  var val3 : String;
  </code></pre>
  
  <p>I want to bind array collection of MyClass objects (two-way) to a form which has a table and another table inside this table.</p>
  
  <p>How can I accomplish that ?</p>
