 Hi All,

 I'm not sure if there is a wicket way to do this, or if I have to mange the
 data myself, but we have a screen that has a select on it and need to detect
 the user changing the value.
 This is simply achieved with a AjaxFormComponentUpdatingBehavior, and works
 well.

 My problem is that by the time MY code gets executed, the component has
 updated the model with the newly selected option, thus losing the existing
 value.

 I'm guessing AjaxFormComponentUpdatingBehavior won't have any way to track
 this change, but is there any other behaviour I can use that allows me to
 see the change in value?

 I hope that makes sense, if not let me know and I'll post a simple example.

 Cheers,
 Steve

Question about Wicket and generics

2010-08-27 Thread Mike Dee

Coming up to speed in Wicket and see some things that I don't know how to
interpret regarding generics.

First, I have a form subclass that looks like this:

private class MyForm extends Form

Eclipse shows the following warning:

Form is a raw type. References to generic type FormT should be
parameterized.

I'd like to try and understand this.  What could T possibly be?

Second, for some things, I'm questioning my understanding of either generics
or Wicket.  Example:

TextFieldString foo = new TextFieldString( foo, model );

But isn't TextField implying text (or a string).  Would TextFieldInteger
make sense (haven't tried it yet)?  If it makes sense, then maybe TextField
is just a bad name and TextField should be thought of as Field?

Just trying to get a grasp on generics in Wicket.  Maybe my grasp on
generics isn't so hot either.

It would be whatever your form is editing.

 But isn't TextField implying text (or a string).  Would TextFieldInteger
 make sense (haven't tried it yet)?  If it makes sense, then maybe TextField

You can have TextFieldInteger, yes.  Wicket uses Converters to
support converting to/from the type needed.

It's certainly possible.  Remember that the type of model that the
form uses would need to be a ModelVoid, though.  For the most part,
your form is going to be modifying something, so it's just easier to
base your form on that type.  So, you'd have, for example:

IModelPerson model = ...;
FormPerson personForm = new FormPerson(personForm, model);
personForm.add(new TextFieldString(firstName, new
PropertyModelString(model, firstName));

Makes sense.  What is the recommended practice when a form is not tied to a

autocomplete for AjaxEditableLabel

2010-08-27 Thread Patrick Petermair

Hi!

Is there a way to enable autocomplete for AjaxEditableLabel (just like 
AutoCompleteTextField)? I was going through AutoCompleteTextField as a 
reference and wrote my own behavior for autocompletion. The new behavior 
works perfectly for a TextField, but not for AjaxEditableLabel.


Any help? What would be the correct way to do it?

Wicket UI Architect / guru needed (Silicon Valley)

2010-08-27 Thread Jennifer Loesch
Wicket UI Architect/Developer
Our Client, a well-known IT company in Silicon Valley, has decided to use 
Wicket to develop an advanced advertising platform that will ultimately be 
utilized by video-streaming companies?the Verizons and Comcasts as well as 
Hollywood and Netflix type firms.  Our Client sees this project as so 
significant that it may become one of the key pillars of the firm in the 
coming years.
Our Client has put together a small RD team to develop middleware to 
address this challenge.  The ideal candidate will have at least 10 years 
of software coding experience which includes 5 years of developing modern 
complex web UIs, an enterprise middleware background and a willingness to 
do product development that goes beyond UI implementation.  At least one 
year of Wicket development/architecting is mandatory.
The developer must be able to work in a fast-paced, Agile environment, 
write clean and solid code and teach/advise other engineers. If you enjoy 
collaborating with a small, entrepreneurial team working on a high 
visibility project, this opportunity is for you!
Developers will work contractually, with an initial commitment of 6 
months.  Compensation included full health benefits.
When we approached Jonathan Locke, he immediately recommended posting on

We do exactly that!  It helps in the case where you need to add
parameters to the search criteria.  You don't have to change your
method signatures in your repository/dao.  It just accepts
MySearchCriteria (or whatever you want to call it).  Then, you have a
FormMySearchCriteria which edits it.

Re: Question about Wicket and generics

2010-08-27 Thread Mike Dee

Trying to understand if there is a pattern here or at least a common way
advanced Wicket users program.  I can see case where the Form may represent
an item in the database and it makes sense to have a corresponding model. 
Is that a Wicket pattern?  This would kind of be like the EJB in J2EE, where
the data item is the entity (and that could be the model).

In my experience, there are lots of other situations too.  For example, we
have lots of forms for doing searches.  The form gathers the search
criteria.  Maybe it would make sense to have a SearchFormCriteria class,
which would be the model?  How are others doing this?

RE: Question about Wicket and generics

2010-08-27 Thread Mike Dee

Does that mean that somewhere (probably internal to Wicket), there is some
place that does something like this: 

X x = MyFormX;

Still having difficulty seeing a case where it is useful to have a situation
that with not FormVoid.  Would like to hear about such a situation.

How to refresh ListView on ModalWindow

2010-08-27 Thread zoran

Hi,

I have a list of products containing a link that should show a user comments
on each product in a modal window. I created a ModalWindow containing a
Panel. I send a list containing comments to this panel. I'm using a ListView
to show this comments e.g:

ListView eachComment=new ListView(eachComment, commentsList){

@Override
protected void populateItem(ListItem item) {
Comment comment=(Comment) item.getModelObject();
item.add(new 
Label(commentContent,comment.getContent()));
}
};

First time I select some product, the list is created in appropriate way.
However, when I close that ModalWindow and open another one for different
product, the first list is shown again. CommentsList containing the comments
is updated before populateItem is called, but it seems that I should make
something more. Do you have any suggestions?

Zoran

Re: How to determine previous value in select after user change

2010-08-27 Thread Steve Mactaggart
That would work I guess, but I don't think it makes sense to build that
logic into the dropdown, this is a function for the model, so I guess if
there are no existing ways to do it i'll have to look at writing a
ChangeTrackedModel or the like to wrap existing models in to manage the
change.

What I really want to be able to do is in the ajax event determine if I want
to allow the user to continue with the change, present them with a dialog or
just cancel the change.

And I wan to be able to just attach this logic to existing components
without having to extend classes all over the shop.

Is there anything like that around?  I've looked through wicketstuff, but
nothing jumped out at me.

Cheers,
Steve

  Hi All,
 
  I'm not sure if there is a wicket way to do this, or if I have to mange
 the
  data myself, but we have a screen that has a select on it and need to
 detect
  the user changing the value.
  This is simply achieved with a AjaxFormComponentUpdatingBehavior, and
 works
  well.
 
  My problem is that by the time MY code gets executed, the component has
  updated the model with the newly selected option, thus losing the
 existing
  value.
 
  I'm guessing AjaxFormComponentUpdatingBehavior won't have any way to
 track
  this change, but is there any other behaviour I can use that allows me to
  see the change in value?
 
  I hope that makes sense, if not let me know and I'll post a simple
 example.
 
  Cheers,
  Steve
