Yes, it just checked that the 1st date (check-in) was in the future
and prior to the 2nd date (check-out).

Is the DatesComparatorValidator object something you wrote or is that
something coming
in wicket 1.3?

Just checked that in (wicket-datetime, CalendarPopup component is now
replaced by behavior DatePicker). Imo, writing it like a behavior is
less elegant than a component, but it's way nicer to use for
end-users.

[Scott Swank]

Now I'm really laughing at myself.  I was reasonably proud of extracting
this.

   private FormComponentFeedbackBorder buildAjaxFeedbackBorder(String
borderId,
   FormComponent component, final FeedbackPanel feedback)
   {
   final FormComponentFeedbackBorder border = new
FormComponentFeedbackBorder(borderId);
   border.add(component);
   border.setOutputMarkupId(true);

   component.add(new AjaxFormComponentUpdatingBehavior("onblur") {
   private static final long serialVersionUID =
-8868206053122717303L;

   protected void onUpdate(AjaxRequestTarget target)
   {
   target.addComponent(feedback);
   target.addComponent(border);
   }
   });

   return border;
   }

Very helpful, thank you.  And yes, you'll get yourself a wiki article out of
the above once I clean it up.

then externalize the feedback border, and make it reusable for the entire
project

class myajaxerrorborder extends formcomponentfeedbackborder {
  private boolean initialized=false;
   public myajaxerroborder(String id) {
super(id);
setoutputmarkupid(true);
}

   protected void onattach() {
   super.onattach();
   if (!initialized) {
  foreach child of type formcomponent in border's hierarchy // use
a visitor {
  child.add(new formcomponentupdatingbehavior() {
   onerror(target) {

);
foreach feedbackpanel in getPage()'s
hierarchy {
target.add(feedbackpanel);
}
}
   }
  }
 initialized=true;
 }
}

so the above border automatically initializes form component children you
add to its hierarchy, it doesnt handle children added after the first
request but it is simple to make it do that, i leave that as an exercise to
you :)

so now we are at:


private void addReservationDates()
{
// create the feedback panel
add(new FeedbackPanel("feedback").setOutputMarkupId(true));

// create the check-in field

DateField checkIn = new DateField("checkIn");
checkIn.add(DateValidator.minimum(getToday()));
add(new MyAjaxErrorBorder("checkInBorder").add(checkIn));

Re: [Wicket-user] ajax libraries & wicket

[Igor Vaynberg]

start with something simple like creating a reusable datetextfield

private static class DateField extends DateTextField {
  public DateField(String id, IModel model) {
super(id, model, "MM/dd/");
setrequired(true);
setoutputmarkupid(true);
   }
}

this will change the code down to:

   private void addReservationDates()
   {
   // create the feedback panel
   FeedbackPanel feedback = new FeedbackPanel("feedback");
   feedback.setOutputMarkupId(true);
   add(feedback);

   // create the check-in field
   DateField checkIn = new DateField("checkIn");
   checkIn.add(DateValidator.minimum(getToday()));
   add(buildAjaxFeedbackBorder("checkInBorder", checkIn, feedback));



// create a date picker for the check-in field
add(new CylleniusCalendar("checkInPicker", checkIn));

// create the check-out field
DateField checkOut = new DateField("checkOut");
add(buildAjaxFeedbackBorder("checkOutBorder", checkOut,
feedback));

// create a date picker for the check-out field
add(new CylleniusCalendar("checkOutPicker", checkOut));

// require checkIn to be before checkOut
add(new DatesComparatorValidator(checkIn, checkOut));
}

private FormComponentFeedbackBorder buildAjaxFeedbackBorder(String
borderId,
FormComponent component, final FeedbackPanel feedback)
{
   ...
}




then externalize the feedback border, and make it reusable for the entire
project

class myajaxerrorborder extends formcomponentfeedbackborder {
 private boolean initialized=false;
  public myajaxerroborder(String id) {
   super(id);
   setoutputmarkupid(true);
   }

  protected void onattach() {
  super.onattach();
  if (!initialized) {
 foreach child of type formcomponent in border's hierarchy // use a
visitor {
 child.add(new formcomponentupdatingbehavior() {
  onerror(target) {
   target.addcomponent(myajaxerrorborder.this);
   foreach feedbackpanel in getPage()'s
hierarchy {
   target.add(feedbackpanel);
   }
   }
  }
 }
initialized=true;
}
}

so the above border automatically initializes form component children you
add to its hierarchy, it doesnt handle children added after the first
request but it is simple to make it do that, i leave that as an exercise to
you :)

so now we are at:


   private void addReservationDates()
   {
   // create the feedback panel
   add(new FeedbackPanel("feedback").setOutputMarkupId(true));

   // create the check-in field

   DateField checkIn = new DateField("checkIn");
   checkIn.add(DateValidator.minimum(getToday()));
   add(new MyAjaxErrorBorder("checkInBorder").add(checkIn));



// create a date picker for the check-in field
add(new CylleniusCalendar("checkInPicker", checkIn));

// create the check-out field
DateField checkOut = new DateField("checkOut");
add(new MyAjaxErrorBorder("checkOutBorder").add(checkOut));

// create a date picker for the check-out field
add(new CylleniusCalendar("checkOutPicker", checkOut));

// require checkIn to be before checkOut
add(new DatesComparatorValidator(checkIn, checkOut));
}



now convert the datepicker from a panel to a behavior - pretty easy to do,
in fact eelco will be doing that today? to wicket-datetime datepicker

so now you will have

private static class DateField extends DateTextField {
  public DateField(String id, IModel model) {
super(id, model, "MM/dd/");
setrequired(true);
setoutputmarkupid(true);
   add(new CelleniusDatepicker());
   }
}

private void addReservationDates()
   {
   // create the feedback panel
   add(new FeedbackPanel("feedback").setOutputMarkupId(true));

   // create the check-in field

   DateField checkIn = new DateField("checkIn");
   checkIn.add(DateValidator.minimum(getToday()));
   add(new MyAjaxErrorBorder("checkInBorder").add(checkIn));



// create the check-out field
DateField checkOut = new DateField("checkOut");
add(new MyAjaxErrorBorder("checkOutBorder").add(checkOut));

// require checkIn to be before checkOut
add(new DatesComparatorValidator(checkIn, checkOut));
}



finally extract a simple daterange panel like jon suggested

and you will be down to:

private void addReservationDates()
   {
   // create the feedback panel
   add(new FeedbackPanel("feedback").setOutputMarkupId(true));

   add(new DateRangeSelector("selector", new PropertyModel(this,
"checkIn"), new PropertyModel(this, "checkOut"), getToday(), null));
}

and what you end up with are new reusable

datefield
ajax error border
daterange selector

Re: [Wicket-user] ajax libraries & wicket

[Jonathan Locke]

well, i find that people often forget how easy it is to subclass components
and create
new ones in wicket.  if your own way of doing date picking is something you
do more 
than twice on your site, a simple panel could collapse all the related
components and
initialization into one little class like DatePickerPanel so a usage of it
looks more like 
the code below and the details of how it works don't bleed out into your
usage code.  
it does take a little bit of fussing to do that, but the code is easier to
work with and 
much more encapsulated.

private void addReservationDates()
{
// create the feedback panel
FeedbackPanel feedback = new FeedbackPanel("feedback");
feedback.setOutputMarkupId(true);
add(feedback);

add(new DatePickerPanel("checkIn", new PropertyModel(roomRequest,
"checkIn")));
add(new DatePickerPanel("checkOut", new PropertyModel(roomRequest,
"checkOut")));

...
}

Cyllenius is a name for the Greek god Hermes -- associated with commerce.
Given the importance of a solid date picker, I imagine we'll be following
and perhaps contributing to this effort.

For anyone using that date picker component, read this:
http://chillenious.wordpress.com/2007/02/06/49/. I hope to see some
more activity/ discussion on that new wicket-datetime project in the
future, and the date picker that ships with that project already is a
lot better than the old one.

Btw, Cyllenius? Where did that come from?

Re: [Wicket-user] ajax libraries & wicket

[Scott Swank]

Briefly, we wanted a component-centric framework for reuse and more nimble
refactoring -- e.g. should this form be in-line with the rest of the page or
in a popup; should this content be in a sequence of panels or in tabs?  This
left us with:

 Tapestry -- we heard daunting things about the learning curve and veered
away
 Echo2 -- excluded our html/css team and required Java changes for too many
UI changes
 GWT -- is not a good fit for non-Ajax apps and we wanted a single
framework

Cheers,
Scott

I'd be interested to learn what you liked and didn't like about those
alternatives (on this list or private).

For anyone using that date picker component, read this:
http://chillenious.wordpress.com/2007/02/06/49/. I hope to see some
more activity/ discussion on that new wicket-datetime project in the
future, and the date picker that ships with that project already is a
lot better than the old one.

Btw, Cyllenius? Where did that come from?

Re: [Wicket-user] ajax libraries & wicket

[Scott Swank]

Igor,

The most verbose code is the following.  It creates the FeedbackPanel and
two fields: a check-in date and a check-out date.  The comments are a bit
heavy because this is a proof-of-concept app.  At this point, and such "best
practices" pointers are more than welcome.  Thank you.

...Oh, and the CylleniusCalendar (our underlying app is named Cyllenius) is
simply a sub-class of DatePicker with a HeaderContributor.forCss() to
increase its z-index a a value greater than that of the ModalWindow from
which it is opened.

   private void addReservationDates()
   {
   // create the feedback panel
   FeedbackPanel feedback = new FeedbackPanel("feedback");
   feedback.setOutputMarkupId(true);
   add(feedback);

   // create the check-in field
   DateTextField checkIn = new DateTextField("checkIn", new
PropertyModel(roomRequest, "checkIn"),
   "MM/dd/");
   checkIn.setOutputMarkupId(true);
   checkIn.setRequired(true);
   checkIn.add(DateValidator.minimum(getToday()));
   add(buildAjaxFeedbackBorder("checkInBorder", checkIn, feedback));

   // create a date picker for the check-in field
   add(new CylleniusCalendar("checkInPicker", checkIn));

   // create the check-out field
   DateTextField checkOut = new DateTextField("checkOut", new
PropertyModel(roomRequest,
   "checkOut"), "MM/dd/");
   checkOut.setOutputMarkupId(true);
   checkOut.setRequired(true);
   add(buildAjaxFeedbackBorder("checkOutBorder", checkOut, feedback));

   // create a date picker for the check-out field
   add(new CylleniusCalendar("checkOutPicker", checkOut));

   // require checkIn to be before checkOut
   add(new DatesComparatorValidator(checkIn, checkOut));
   }

   private FormComponentFeedbackBorder buildAjaxFeedbackBorder(String
borderId,
   FormComponent component, final FeedbackPanel feedback)
   {
   final FormComponentFeedbackBorder border = new
FormComponentFeedbackBorder(borderId);
   border.add(component);
   border.setOutputMarkupId(true);

   component.add(new AjaxFormComponentUpdatingBehavior("onblur") {
   private static final long serialVersionUID =
-8868206053122717303L;

   protected void onUpdate(AjaxRequestTarget target)
   {
   target.addComponent(feedback);
   target.addComponent(border);
   }
   });

   return border;
   }

got any examples of this verbouse code? i am doing something similar in a
project i am building with 2.0 and i was able to factor out a lot of this
stuff so its not so bad. maybe we can help you do the same.

Re: [Wicket-user] ajax libraries & wicket

[Scott Swank]

Thank you very much Eelco.  And yes, the JSF development has been very
impressive -- it was our 2nd choice after considering a host of other
options, including Stripes, Rife, Tapestry, Echo2, GWT, etc.  And yes, I
imagine I need to start at least lurking on ##wicket.

Cheers,
Scott

Let's not forget b.t.w. that there is a lot of free-time sweat and

- even though JSF doesn't have my preference - I think it is still a
better alternative than say Struts. But that said, I hope we'll see a
lot of you and your team members around here and on the ##wicket

now (I know that I do :))
