Date formatting in screen

I want to display the date like this “Mar/2016”

tried as follows in the screen xml

 <dateField id="month"
                       width="300px" dateFormat="mmm/yyyy"/>

It doesn’t show anything in the dateField.

When I use the dateFormat “dd/mm/yy” it only shows 17/ (today) without month and year.

Month in the dateField could be displayed only in 2-digit format.
For correct displaying of custom dateFormat(like dd/mm/yy), specify also the ‘resolution’ property.
The following should work well:

 <field id="dateBox"
                       resolution="MONTH" />

  <field id="dateBox"
                       resolution="DAY" />
