Object values trim white-space - causes problems for date objects

Trying to achieve this for the value of a Ext.field.Datepicker:

Code:

---

{
        year: new Date().getFullYear(),
        month: (new Date().getMonth() + 1),
        day: new Date().getDate()
}

---

The output code becomes:

Code:

---

{
        year:newDate().getFullYear(),
        month:(newDate().getMonth()+1),
        day:newDate().getDate()
}

---

I guess it shouldn't be trimming whitespace as minification of the application will sort that out anyway
