So basically I could subclass DatePicker and override
getAdditionalJavascript to inject some Js that triggers the onchange
event in DateTextField when some useful event in DatePicker fires.
I also found the appendToInit method below, but that method is never
called in DatePicker. Would that be a bug?

/**
* Append javascript to the initialization function for the YUI

* subclasses to conveniently extend configuration without having to

*
* @param markupId
* The markup id of the calendar component
* @param javascriptId

* @param javascriptWidgetId

*/
protected void appendToInit(String markupId, String javascriptId,
String javascriptWidgetId,
StringBuffer b)
{
}
/**

* }
* </pre>
*
* @return a String containing additional Javascript code
*
*/
protected String getAdditionalJavascript()
{
return "";
}

i dont think values changed via js send out onchange events. you will
probably need to hook into the datepicker javascript and invoke
onchange explicitly. fortunately yui stuff has a pretty good event
system that widgets use, so plugging into it should probably not pose
a huge problem.

Hi all,
I'm currently having some trouble with a DateTextField. The
DateTextField has a DatePicker component attached to it.
Once the user changes the date with the DatePicker, the attached
DateTextField is assigned the new date and should trigger the onChange
event. Which it doesn't do....
Everything works fine if the date is changed by typing directly it into
the textfield. Any ideas?
DateTextField dtf = DateTextField.forShortStyle("dateField", new
PropertyModel(this, "date"));
dtf.add(new DatePicker());
OnChangeAjaxBehavior dateOnChange = new OnChangeAjaxBehavior() {
@Override
protected void onUpdate(AjaxRequestTarget target) {
log.debug("dateField onChange event triggered.");
// do some stuff with the date here...
}
};
dtf.add(dateOnChange);
add(dtf);
