Re: WICKET-5083 and Page.isPageStateless
So, I've started to figure out which of our components tries to access our Model in #onInitialize. It ended up that almost every component does. This means, that I have to re-write all these components which might be very time consuming. I'm wondering why a request with a redirect has to initialize all these components before doing the actual redirect.

Re: jquery dialog onclick AjaxButton
Hi, In addition, wicket-jquery-ui provides a confirmation button (ConfirmButton / ConfirmAjaxButton) which already handles a confirmation jQuery UI dialog. http://www.7thweb.net/wicket-jquery-ui/button/ConfirmButtonPage If you need inspiration on how jQuery UI dialog's buttons are handled, you can have a look at: https://github.com/sebfz1/wicket-jquery-ui/blob/master/wicket-jquery-ui/src/main/java/com/googlecode/wicket/jquery/ui/widget/dialog/DialogBehavior.java Best regards, Sebastien.

It is necessary to detect whether a page is stateful before redirecting to it.

how to add select/deselect all checkbox to wicket DataTable
Hi All,
I'm trying to add select All Checkbox to the header of wicket DataTable
column, I've read that I need to use CheckGroup and CheckGroupSelector. I'm
doing the following:
Form form = new Form(form);
CheckGroup group = new CheckGroup(group);
group.add(new CheckGroupSelector(groupselector));
DataTable sourceTable = new DataTable(mytable, getColumns(),
getDataProvider(), 10);
sourceTable.setOutputMarkupPlaceholderTag(true);
group.add(sourceTable);
add(form);
form.add(group);
private List getColumns() {
ListIColumnlt;MyItem, String ret = Lists.newArrayList();
ret.add(new AbstractColumnMyItem, String(new Model()) {
@Override
public void populateItem(ItemICellPopulatorlt;MyItem
cellItem, String componentId, IModelMyItem rowModel) {
CheckBoxPanel checkBoxPanel = new
CheckBoxPanel(componentId);
cellItem.add(checkBoxPanel);
}
});
...
}
input type=checkbox wicket:id=groupselectorcheck/uncheck all/input
[Lookup Results]
To add CheckBox to the DataTable I must use a Panel, so I have the
following:
public class CheckBoxPanel extends Panel {
private CheckBox field;
public CheckBoxPanel(String id, IModelBoolean model) {
super(id);
field = new CheckBox(checkBox, model);
add(field);
}
public CheckBoxPanel(String id) {
this(id, new ModelBoolean());
}
public CheckBox getField() {
return field;
}
}
In CheckBoxPanel.html
body
wicket:panel xmlns:wicket=http://wicket.apache.org;
input type=checkbox wicket:id=checkBox
/wicket:panel
/body
Actually it does show checkgroup but under my table and checking/un-checking
it does not affect the check boxes under it. What am I doing wrong here?

RE: how to add select/deselect all checkbox to wicket DataTable
I would reconsider your use-case.
Select all for what? All results on a single page? All results for the
entire data table? All results that are filtered? Select all on this page,
then more on the second page?
I added a SelectAllPanel which allows you do to all of the above. Perhaps I
should share it with the WicketStuff's extension project if one does not
already exits.
~ Thank you,
Paul Bors

Hi, Wicket doesn't use commons collections - check which maps you pass into components or models.

I think this is something browser related, IE while deciding which rendering technique to adopt can do strange queries. It could be interesting if you dumped what happens on network using IE or another "working" browser with your old non working code.Regards, __Cedric Gatay (@Cedric_Gatay)http://code-troopers.com|http://www.bloggure.info|http://cedric.gatay.fr On 15 juillet 2013 at 20:35:40, prasad.bhandagi (prasad.bhand...@marsh.com) wrote: Using the DOCTYPE of HTML 4.01 STRICT worked !

Form questions
Hello,
I'm interested in creating a single Form that will accommodate the
following use cases
1) display blank for creating new records
2) pre-populate for editing existing records
3) map submitted values on to an existing domain object
4) accommodate two actions, Save Draft -or- Publish
I'm following Wicket in Action and within my Form constructor I create my
model, like this
CnavUrl cnavUrl = new BasicCnavUrl();
IModel model = new Model((Serializable) cnavUrl);
setModel(model);
I then use PropertyModel
add(new TextField(url, new PropertyModel(cnavUrl, url)));
For the two actions, I'm creating the Button objects like this
add(new Button(publish, model) {
@Override
public void onSubmit() {
CnavUrl cnavUrl = (CnavUrl) getModelObject();
System.out.println(publish);
}
});
Some problems I can't figure out. The code to create the button complains
that it requires a CnavUrl but gets back a String.
It seems that a new BasicCnavUrl is created once with the Form. What
happens on subsequent calls? Can I always expect my model to have the data
from the current form submission?
Is there a best way to incorporate the idea of an edit, where the model is
pre-populated from a data source and pre-fills the Form fields?
Thanks,
Daniel
RE: Form questions
On wicket's home page http://wicket.apache.org to the left there is a Learn
- Books section.
Under the Books page the first book is Wicket free guide.
Download it and read chapter 9 and 10 if not the entire book.
You might be interested in section 9.2 Models and JavaBeans and 9.3.1
Form and models in particular.
In short... an empty form field has a null model object (or empty string)
and to pre-populate have your POJO that you use as a model object have its
instance variables populated with the values you want (from a db or etc).
~ Thank you,
Paul Bors
