Several issues:
1) The repeating view should be associated with each item in the list,
not the list itself.
2) If you delete an item from the list, you have to refresh the whole
list.
3) To delete an item, you need to delete your "person" component (the
parent of the ajax link), not the ajax link itself.
Here is some sample code that works:
-.
delete
01
public class Group extends WebPage {
public Group() {
final WebMarkupContainer pl =
new WebMarkupContainer("personalList");
pl.setOutputMarkupId(true);
final RepeatingView v = new RepeatingView("person");
for (int i = 0; i < 3; i++) {
WebMarkupContainer p =
new WebMarkupContainer(Integer.toString(i));
p.add(new AjaxLink("delPerson") {
public void onClick(
AjaxRequestTarget target) {
v.remove(getParent());
target.addComponent(pl);
}
});
p.add(new Label("idPerson", Integer.toString(i)));
v.add(p);
}
pl.add(v);
add(pl);
}
}

Re: [Wicket-user] How to auto-eliminate component from RepeatingView
Well, if I understood it right, then its quite easy:
you have a "personalList" where you add(Component c) to - you can replace
that by
addOrReplace(Component c) and if there is a Component with Tag "foo" there
then it will be replaced, else it will be put to it.
You can also use .remove(Component C) or .remove(String id) to remove a
component whose given IDs match - so, the .remove would be the answer to
your question.
Be sure to checkout the examples at:
http://wicketstuff.org/wicket13/
and especially:
http://wicketstuff.org/wicket13/repeater/
and how AJAX should work, as your AJAX code looks quite odd to me
http://wicketstuff.org/wicket13/ajax/
(to use AJAX you need to manipulate the markupcontaier wich doesnt work with
a repeater like ListView or RepeatingView unless you span a
WebMarkupContainer around it - explained in wiki:
http://cwiki.apache.org/WICKET/how-to-repaint-a-listview-via-ajax.html )
However, i suggest you to get it working with a usual Link first, and then
try to AJAXify it,
Regards

Betreff: [Wicket-user] How to auto-eliminate component from RepeatingView
Hi, I'm new to wicket and I'm trying to do a sort of nested list of
components, but each
list's item (component) has not just info about the model, but also has
links to delete/modify
itself from the list...
so I have this html code...
Group.html:
and Person.html:
-.
01
So the Group.java gets the PersonModel and adds a new Person component to
the RepeatingView...
RepeatingView personalList = new RepeatingView("personalList");
for (Iterator iter = personalModelList.iterator(); iter.hasNext();)
{
PersonModel personModel = (PersonModel) iter.next();
final Person oPerson = new Person("person", personModel);
personalList.add(oPerson);
}
add(personalList);
My question is this:
How can I do to make the "delete this person" works in order to get it
removed from the RepeatingView?
I was trying this code inside the Person.java so the component (item from
the list) can activate the auto-remove
from the list, but doesn't work:
final AjaxLink delPersonaRel = new AjaxLink("delPersonLink"){
public void onClick(final AjaxRequestTarget target)
{
getParent().remove(this);
System.out.println("person deleted");
target.addComponent(getParent());
}
};
Any suggestion appreciated.
