public class AjaxDatePicker
extends AjaxComponent

Shameless port and adoption of Rails Date Kit. This input understands the format symbols %A, %d, %e, %b, %m, %B, %y, and %Y. See the NSTimestampFormatter for what these symbols do. This component can also understand the corresponding symbols from java.text.SimpleDateFormat. The translation from SimpleDateFormat symbols to NSTimestampFormatter symbols may have some defects.

Only one of format or formatter may be bound, if both are unbound the default of %m %d %Y is used. If format is bound, the pattern is used to create an internal formatter for validation. If formatter is bound, its pattern is extracted and used in place of format. The format/formatter is used to control the initial display in the input, the format of the value that the date picker places into the input, and validation of the input contents on form submission. The use of formatter over format is preferred for reasons of efficiency and localization.

FL: The component uses the default Locale to determine the start day of the week. It also uses the current language in ERXLocalizer to translate the day and month names (you must set up the localizations).

NOTE: the AjaxDatePicker does NOT play nice with the AjaxModalDialogOpener. There is some sort of initialization conflict (I think) with Prototype that leaves you with a blank page and the browser waiting forever for something (and I have not been able to determine what it is) as soon as calendar.js loads and initialized. It will work if the page the AMD appears on explicitly loads the calendar.js in it's HEAD:

  public void appendToResponse(WOResponse response, WOContext context) {
       super.appendToResponse(response, context);
       ERXResponseRewriter.addScriptResourceInHead(response, context(), "Ajax", "calendar.js");
   }

Bindings

Name	Description
value	the value that will be shown in the input field and set by the date picker (required)
format	the format to use in the input field (only one of format or formatter may be bound)
formatter	the formatter to use with the input field (only one of format or formatter may be bound)
id	HTML ID passed to the input field
class	CSS class passed to the input field
style	CSS style passed to the input field
size	size attribute passed to the input field
maxlength	maxlength attribute passed to the input field
name	name attribute passed to the input field
disabled	passed to the input field
onDateSelect	JavaScript to execute when a date is selected from the calendar
fireEvent	false if the onChange event for the input should NOT be fired when a date is selected in the calendar, defaults to true
manualInput	false if you want to prevent manual input from the user and force him/her to use the date picker, defaults to true
startDay	specify the first day of week to use 0(Sunday)-6(Saturday). The default use the current localizer.
