nice. why not on wicketstuff?
I'll be glad putting it there. It's my intention.
I've checked out wicketstuff. Should I just add my code and check in?
Who should I contact to about this?

1st: afaik you should not use
$(document).ready(... as it would break compatibility with other JS
frameworks redefining the $
jQuery(document).ready(...
or
(function($) { /* some code that uses $ */ })(jQuery)
would be better. please keep in mind, you only contribute one component
to the page, so there might be a bunch of others ;)
I am a totally newbie in the JS domain so your ramark really helps me
learning this stuff.

as it is a good practice to add functions (aka plugins) to the jQuery
object, including the jQuery script more than once in a page is not only
useless waste of bandwidth and lowers user experience, but does
severel harm (last wins).
I think that when I add it to the wicketstuff-jquery module, this problem
will vanish.
I've noticed that the parent behavior of the Wicket-JQuery checks (in the
responseHead method) checks if it's already been added.
My behavior will extend this one so it shouldn't harm anything.
Or am I wrong?

oh, and PS: i don´t get LockButton/ResetButton/validate in the global

I'll look into that as well.
And many thanks.
I'll tell you the truth, I'm pretty exited adding a (even as small as it is)
module and to contribute something I picked up...

Reading an attribute that is set in a CSS file as a class
Hello,
Suppose I have a CSS file that is used in our application (HeaderContributer
etc.)
In this file I have many classes.
Suppose I want to get an attribute that is in one of these classes.
Example:
In my CSS file I have:
...
.colored-table {
border: thin;
background-color: #BB
...
}
I want in Wicket code something like:
getClassAttributeFromCss(CSS_File, attributeName).
And, putting in CSS file the location of that file (same methods as in the
HeaderContributor.forCss).
Putting background-color in the second parameter.
Result: #BB
Is it possible?

Steve Swinsburg-2 wrote: On your component attach an AttributeAppender or AttributeModifier, set the class attribute to be the name of your class. Done :) Thanks Steve but this is not what I meant.

DataTable - tfoot before tbody?
Hi,
I have a customized DataTable.
Here's what we have in the constructor:
super(id, columns, dataProvider, rowsPerPage);
add(HeaderContributor.forCss(/eurekify/style/EurekifyDataTable.css));
add(new AttributeAppender(class, true, new
Model(eurekifyTable),
));
addTopToolbar(newNavigationToolbar());
addTopToolbar(newHeadersToolbar(dataProvider));
addBottomToolbar(new NoRecordsToolbar(this));
addBottomToolbar(new EurekifyBottomTableToolbar(this,
rowsPerPage,
modalWindows,
showSelectRecordsPerPage));
add(new AttributeAppender(class, true, new
Model(emptyTable), ) {
private static final long serialVersionUID = 1L;
@Override
public boolean isEnabled(Component component) {
return dataProvider.size() == 0;
}
});
More info:
newHeadersToolbar(...) returns AjaxFallbackHeadersToolbar (which is
HeadersToolbar)
newNavigationToolbar(...) returns StyledAjaxNavigationToolbar which inherits
from AjaxNavigationToolbar (which is NavigationToolbar).
EurekifyBottomTableToolbar inherits from AbstractToolbar.
When I look at FireBug, I see that the tfoot section of the table is BEFORE
the tbody.
Has anyone encountered this?
Do I do something wrong?

Confused
Hi,
I have a page that holds a list (of Strings).
In the constructor, I initialize the list.
Then I call a Panel with this list to create a ListView of something.
In a Modal window I set the list to have data in.
The problem is that the list is initialized whenever I refresh the page (F5)
(the Page's constructor is called).
How can I pass this problem.
Where should I keep a model that holds the list data?
Some code:
... Class members:
private ListString linksIds;
private final LinksPanel linksPanel;
... In the constructor:
super(id);
setOutputMarkupId(true);
linksIds = new LinkedListString();
...
linksPanel = new LinksPanel(links, getLinksIds());
...
The getters and setters:
public ListString getLinksIds() {
return linksIds;
}
public void setLinksIds(ListString linksIds) {
this.linksIds = linksIds;
linksPanel.setLinksByIds(linksIds);
}
The setter is called when the user press OK in a Modal window.
The list is changed and the UI changes Ajax-ly. So this is OK.
The only problem is refreshing the Page.
Thanks for any help,
-

Re: Confused
Thanks Martin,
That really helped. Though I did something else and now I have a new
problem.
It's an Ajax problem now.
Here's what I did:
In the constructor:
idsModel = new LoadableDetachableModel() {
private static final long serialVersionUID = 1L;
@Override
protected Object load() {
ListString ids = new ArrayListString();
ListProperty properties =
sageDal.getPreference(userId,
SETTINGS_GROUP,
HomePageSectionPanel.this.sectionId);
for (Property property : properties) {
ids.add(property.getValue());
}
return ids;
}
};
linksPanel = new LinksPanel(links, idsModel);
I am adding the ListView in LinksPanel:
private void init(final ListLinkContainer links) {
add(new LinksListView(listview, new AbstractReadOnlyModel() {
private static final long serialVersionUID = 1L;
@Override
public Object getObject() {
return links;
}
}));
}
(I have a method that changes the String ids to the LinkContainer).
My problem is when setting new list.
Here is my code:
public void setLinksIds(ListString linksIds) {
sageDal.setPreference(userId, SETTINGS_GROUP, sectionId,
linksIds.toArray(new String[0]));
}
It works and I actually see the change in the database. When refreshing (or
checking in the DB) I see changes.
BUT, it doesn't change automatically.
I use a ModalWindow and here's where I add my panel to the modal:
setWindowClosedCallback(new ModalWindow.WindowClosedCallback() {
private static final long serialVersionUID = 1L;
public void onClose(AjaxRequestTarget target) {
target.addComponent(homePageSectionPanel);
}
});
I'm sure I need to add something else somewhere.
But what? and where ?
Thanks,
Eyal

Hi!
Here is a good example of a list model:
public abstract class AbstractListChoiceModelS extends
AbstractReadOnlyModelList? extends S {
@Override
public final ListS getObject() {
return getChoices();
}
public abstract ListS getChoices();
}
Now change your code as follows:
linksPanel = new LinksPanel(links, new AbstractListChoiceModelString()
{
@Override
public ListString getChoices() {
// Where did you get your choices in the first place?
}
} );

Re: Palette within a ModalWindow
Hi, Can you send a code example of how you have used the setContent , ModalWindow and Pallete all together? I used the same as the examples of ModalWindow with a Page. And the Page has the Pallete. There aren't many examples of Palette. Thanks, Eyal Kai Mütz (Old) wrote: Hi, I want to realize a palette within a ModalWindow. I have subclassed the ModalWindow and added a palette with the setContent() method. This works actually, the model is updated with the selected choices after closing the modal window and submitting the form. - Eyal Golan [EMAIL PROTECTED] Visit: http://jvdrums.sourceforge.net/ http://jvdrums.sourceforge.net/ LinkedIn: http://www.linkedin.com/in/egolan74 href=http://www.linkedin.com/in/egolan74 -- View this message in context: http://www.nabble.com/Palette-within-a-ModalWindow-tp15829096p18071792.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: isVisible vs. setVisible
Yes but ... isVisible may be triggered several times, while setVisible should only be called once (say if I do it only once after creating the component). Usually I prefer the state driven way, but what if the logic has a lot of overhead? Jonathan Locke wrote: isVisible is generally better imo because it is state driven. if you push instead of pull, the state can get stale. - Eyal Golan [EMAIL PROTECTED] Visit: http://jvdrums.sourceforge.net/ http://jvdrums.sourceforge.net/ LinkedIn: http://www.linkedin.com/in/egolan74 http://www.linkedin.com/in/egolan74 -- View this message in context: http://www.nabble.com/isVisible-vs.-setVisible-tp17860615p17860930.html Sent from the Wicket - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
