Description

Accessing the value property of using the getValue func of a picker always returns undefined

var win = Ti.UI.createWindow({
  exitOnClose: true,
  layout: 'vertical'
});

var picker = Ti.UI.createPicker({
  top:50
});

var data = [];
data[0]=Ti.UI.createPickerRow({title:'Bananas'});
data[1]=Ti.UI.createPickerRow({title:'Strawberries'});
data[2]=Ti.UI.createPickerRow({title:'Mangos'});
data[3]=Ti.UI.createPickerRow({title:'Grapes'});

picker.add(data);
picker.selectionIndicator = true;

win.add(picker);
win.open();
var showDate = Ti.UI.createButton({
    title: 'get value',
    bottom: 20
});
showDate.addEventListener('click', function(e) {
    console.log('.value ' + picker.value)
   console.log('getValue ' + picker.getValue());
});

picker.addEventListener('change', function(evt) {
    console.log('Changed ' + evt.value);
});


win.add(showDate)

Repro steps

This seems to work fine for date pickers

   var _window = Ti.UI.createWindow();
   var datePicker = Ti.UI.createPicker({
       type: Ti.UI.PICKER_TYPE_DATE,
       useSpinner: false
   });
   
   datePicker.addEventListener('change', function(e) {
       Ti.API.info('change event: value = ' + e.value);
   });
   
   var button = Ti.UI.createButton({
       title: 'Get value'
   });
   
   button.addEventListener('click', function() {
       Ti.API.info(datePicker.value);
       Ti.API.info(datePicker.getValue());
   });
   
   _window.add(datePicker);
   _window.add(button);
   _window.open()

According to the [API doc](http://docs.appcelerator.com/platform/latest/#!/api/Titanium.UI.Picker-property-value), value only works with date and time pickers. I also tested the test code on iOS and it returns undefined, so I would think this is not a bug. [INFO] .value undefined [INFO] getValue undefined
