title: How to add datefield in datagrid
body: <p>I have a datagrid with editable property and inside a column to display date information.
  Dates are storing in a dataprovider as string format. (those dates come from database with httpservice).
  But I'd like to add an itemEditor on my datagrid column.
  To do that, I try </p>
  
  <pre><code> &lt;mx:DataGridColumn dataField="echElemDate"  headerText="MyHeaderDate" 
       headerStyleName="dgHeader" fontWeight="normal" 
        itemEditor="mx.controls.DateField" editorDataField="text"/&gt;
  </code></pre>
  
  <p>But when I click on this cell, an error appear :</p>
  
  <pre><code>Type Coercion failed: cannot convert "29/07/2015" to Date
  </code></pre>
  
  <p>So can you help me to solve this mistake.</p>
  
  <p>Thanks</p>
