I created a test handler with this widget and in preview tab when I change the date manually and put 30/2/2016 and click tab it gives no error.
testDateBox DojoDateTextBox{ layoutData = new GridLayoutData{ row = 2, column = 2 }, formatLength = DojoLib.DATEBOX_FORMAT_SHORT, value = new Date{} };
How is its possible to validate the input date?
