Description

I'm running:

Titanium SDK Version: 1.4.0
Iphone SDK Version: 3.2/4.0
Titanium Developer: 1.2.1

Unfortunately i cannot use this simple code to get the value of a datepicker:

var myDatePicker = Ti.UI.createPicker({
    type:Ti.UI.PICKER_TYPE_DATE_AND_TIME,
    top: 0
});

debug( myDatePicker.value ); // returns null

KitchenSink shows how to get the value with an event ( and it works! ), but not when you need it outside an datepicker's event.

I've also seen this issue.

The workaround is manually updating the picker's value inside an onChange callback:
```
   picker.addEventListener('change', function(e) { picker.value = e.value; });
   
```

Continuously get 'null' using the following sample code - maybe another Apple bug regarding the date picker? Wouldn't be the first time.

   var win = Ti.UI.createWindow({backgroundColor:'white'});
   var myDatePicker = Ti.UI.createPicker({
       type:Ti.UI.PICKER_TYPE_DATE_AND_TIME,
       top: 0
   });
   
   Ti.API.info('Pre-add value: '+myDatePicker.value);
   win.add(myDatePicker);
   Ti.API.info('Post-add value: '+myDatePicker.value);
   
   win.addEventListener('focus', function() {
       Ti.API.info('Focus value: '+myDatePicker.value);
   });
   win.addEventListener('open', function() {
       Ti.API.info('Open value: '+myDatePicker.value);
   });
   
   win.open();
   
   var timer = setTimeout(function() {
       Ti.API.info('Timer value: '+myDatePicker.value);
   }, 1000);

   Titanium.UI.setBackgroundColor('#000');
   
   var win1 = Ti.UI.createWindow({
   	backgroundColor:'white',
   	fullscreen:false,
   	exitOnClose:true
   });
   
   var minDate = new Date(2011,11,1);
   
   var maxDate = new Date(2012,11,31);
   
   var value = new Date();
   
   var picker = Ti.UI.createPicker({

   picker.setLocale('fr');
   Ti.API.info('The current picker value is: ' + picker.value)
   win1.add(picker);
   
   win1.open();
