There already was report of this problem here: https://www.sencha.com/forum/showthr...teEdgePicker(). But it is still not fixed.

To the point, in `Ext.field.Date.createEdgePicker` there's call to method `Date.getFullyear` which throws error, because there's no such method(or rather, there's method with name `getFullYear`). Please fix.
