DateField not picking a date from its header menu

[blay]

Hello:

I have this method:


public static DateField createDateStart(){

DateField dateField = new DateField();
dateField.getPropertyEditor().setFormat(
DateTimeFormat.getFormat("dd/MM/y"));

dateField.setFieldLabel(messages.dateStartLbl());
dateField.setLabelSeparator("");
return dateField;
}

The DateField created works fine except when you click on the header menu (just between the arrows for next and previous month), so a menu appears with all months and some years, You can select any combination but when you click ok, nothing happens, I mean, no date is loaded into the dateField box.
Any idea?

Works fine for me on that page.

In fact, comparing that DateField from mine, mine doesn´t show the month and year on the header (just a blank box). Then if you click (and the months and years appear) the right month and year are selected, but changing that selection and clicking ok does nothing...
I´ve been checking any posible mistakes and I don´t find what happens...

Can you please post a fully working testcase that implements EntryPoint and shows your problem?
