title: ExtJs 3.4 : Set String type date as the value of a date field
body: <p>I have Json data which is retrieving from database by sending an Ajax request.</p>
  
  <pre><code>{'tourData':[{ 'code' : '6', 'ref' : '22/01/2014 09:08:54-Route 2', 'vehicle' : 'GY-122-120', 'fromDate' : '2014-01-22 00:00:00', 'toDate' : '2014-01-22 00:00:00', 'tourAssign' : 'Saman', 'driver' : 'Kamal Subhasingha', 'assistant' : 'Sampath Jayaweera', 'porter1' : 'Namal Witharana', 'porter2' : 'Yohan', 'porter3' : 'Ahan Liyanage' } ]}
  </code></pre>
  
  <p>I try to set 'fromDate' as the value of a date field.</p>
  
  <pre><code>new Ext.form.DateField({
          id : 'fromDateCombo',
          fieldLabel : 'From Date',
          allowBlank : false,
          width : 140,
          name : 'fromDate',
          emptyText : 'From Date',
          hideLabel : true,
          format: 'd/m/Y',
          style : 'marginleft:10px',
          disabled : true,
          listeners : {
              select : function() {
                  if (Ext.getCmp('toDateCombo').getValue()&lt; this.getValue()) {
                      Ext.Msg.show({
                            title: 'Error',
                            msg: 'From Date should be less than or equal To Date' ,
                            buttons: Ext.MessageBox.OK,
                            icon: Ext.MessageBox.ERROR
                      });
                      this.setValue(sysDate);
                  } 
              }, render: function(c) {
                  new Ext.ToolTip({
                      target: c.getEl(),
                      html: 'From Date'
                  });
              }
  
          }
      });
  </code></pre>
  
  <p>I've tried this.</p>
  
  <pre><code>var jsonData = Ext.util.JSON.decode(response.responseText);  
                              console.log(jsonData);
                              if (jsonData.tourData.length &gt; 0) {
  
                                  Ext.getCmp('fromDateCombo').setValue(Date.parseDate(String(jsonData.tourData[0].fromDate), 'd/m/Y'));
  
                              }
  </code></pre>
  
  <p>But it doesn't set the date and doesn't print any error message in my firebug console.</p>
  
  <p>What's wrong with my codes and how can I fix it ?</p>
  
  <p>Kind Regards</p>
