clear date with datetimepicker struts 2

[Cesar Coz]

does anyone knows how to clear the textfield of the datetimepicker tag on struts 2 ?

im trying with this:

  
 var fechaOperacion = dojo.widget.byId("fechaOperacion");
 fechaOperacion.setValue('');

its not working

and with this:

  
<s:datetimepicker name="fechaOperacion"
displayWeeks="4" 
displayFormat= "MM-dd-yyyy"/>

var ud = getField('form', 'fechaOperacion');
ud.value = "";
  

but does not work either

can anyone help me ?

Value you are setting must be parsable as date object.

oh i see...

well if i cant set the value to null or empty maybe there is a way to clean the field.. anyone?

Try it.
I guess it would have the value as January 1, 1970 00:00:00.000 GMT.
