(issue1762) Use getValue to obtain dateRange values The getToValue was always the initial value regardless of what has been entered in the form. According to the documentation both getToValue and getFromValue should return the "initial value" of the form field. But wether this means the value before validation corrections or the value the field is initialized with (which is also not true in both cases as the field is set only after creation) It returned the real value for the from date but not for the to date. With an explicit getValue we workaround this issue.
