For a date field suppose you have the folowing value:
Now paste some text (from clipboard) in that field. For example, after pasting some text, i have:
(I suppose the date field is mandatory)
Now press tab, the calendar will popup, select a correct date and press ok.
Here some strange things happen:
* the date is not corrected
* if you are using a new row (not saved), and press undo (or ESC) the field remains
* and so on....
