[CLOSED] GXT 1.1.2: DateField does not fire Change Event

[firejack]

I am finding that DateField objects do not seem to fire change events when they are updated. I am trying to use change listeners to keep field values in sync with model values in a uniform way, but DateFields don't seem to want to cooperate.

Here is a simple example.

FormPanel fp = new FormPanel();
final DateField df = new DateField();

df.addListener(Events.Change, new Listener() {

public void handleEvent(FieldEvent p_event)
{
MessageBox.alert("Date Field Changed", df.getValue(), null);
}

});

The change event never fires when I render this guy. In addition, I have tried firing the change event myself from the setValue() method, but that seems to wreak havoc with the widget a bit. Not sure why, but I am looking at the internals now.

Please post complete test code when submitting a bug as it make it much easier to replicate the issue.

For example:

  public void onModuleLoad() {
    FormPanel fp = new FormPanel();
    DateField df = new DateField();
    df.addListener(Events.Change, new Listener<FieldEvent>() {
      public void handleEvent(FieldEvent p_event) {
        Window.alert("change: " + p_event.value);
      }
    });
    fp.add(df);
    RootPanel.get().add(fp);
  }

The change events fires when the field is blurred, not when the user selects a value from the date picker. I did find a bug. In some browsers, if you did not put focus on the text field before clicking the trigger the change event did not fire. This is fixed in SVN.

Darrell -

No problem on the code examples. Thanks a ton for getting those fixes in. This one and the resize issue fixed me right up. Much appreciated.

but what about if you want the event to fire on change (that is once user has clicked a date on the datepicker) and you DO NOT want to have to wait for blur to occur ????

There is a solution :

        DateField startDate = new DateField();
        startDate.getDatePicker().addListener(Events.Select, new Listener<DatePickerEvent>() {

            public void handleEvent(DatePickerEvent be) {
                // TODO Auto-generated method stub
                //On Select event :)
            }
            
        });

Is it possible to auto-blur the DateField when the picker fires a selected event?

I can only find a way to focus another field, but it would be best if the field could be de-focused automatically.
This would allow the change event to fire, and also stop users accidentally typing in the field once they have selected a date.
