Thanks Pedro, it's ok now ;-)
I use LoadableDetachableModel to avoid the call to detach() method. It
does not seem that is the right way. Somebody can explain me why ?

Pedro Santos a écrit :
by calling getDefaultModel inside onClick, you get an reference to the link
component model. You need to detach the model on your list view. You has an
reference to it on your variable "news". So: news.getDefaultModel().detach()
If you need, you can change that variable modifiers or turn it an instance
variable for have acess to it inside your onClick implementation.

The behaviour is the same with the following code :(
public void onClick() {
// TODO : check the refresh issue
getNewsDao().delete(item.getModelObject());
ourLogger.debug("News deleted");
getDefaultModel().detach();
}

missing line: call detach method just after delete your item.

Call news.getDefaultModel().detach(), and look for more info about

Hi,
I don't use Hibernate. My persistence layer uses JDBC.
What is strange when I click the delete link, it's the logs order :
Loading all news
News deleted
So it seems that the deletion is done after the data reload :(

Stephane,
I'll let someone smarter than me address the wicket issue of removing
the
item from the ListView and seeing if that helps -- but is there a
chance
you
are using Hibernate and the Level 2 ehcache plugin or any 2nd-level
caching
with your persistence code? I ask because I've seen code like this "I
don't
see my changes until the 2nd refresh!" a lot with folks using 2nd level
caches and not seeing immediate persistence of those changes.

You're probably not using models correctly - specifically for your
list
view. You could post some code, but make sure that you're reloading
the
data for the list view after the onClick is called and the item is
deleted.

Hello,
My page displays a list of items, for each of them, an icon is
available
to
delete it. The action is managed in a Link.onClick() method.
When I click on the link, the page is refreshed but the item is
always
in
my list, I have to do refresh again manually the page to have a list
wihtout
this item.
In the logs, it seems that the deletion in the onClick() method is
called
after the load of the page :(
Somebody has an idea to avoid this manual refresh ?
Thanks,
Stéphane
