It is natural:
1 - model load some data from some source
2 - that source was updated, changed, and the data loaded on the model no
more reflect the data on that source
3 - detach the old loaded data on model
4 - next time any object require the data on model, it will no longer have
the old data
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
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.

Please find my code just below :
public class NewsListPage {
protected static transient NewsDao myNewsDao;
public NewsListPage() {
PageableListViewNews news =
new PageableListViewNews(list, new NewsModel(), 15){
@Override
protected void
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
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 :(

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

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

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);
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
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 ?

Seems weird to me as well that 'detach' has to be explicitly called. Also
still curious why Stephane was seeing the log ordering he did when the link
was clicked:
Loading all news
News deleted
I'd expect to see news deleted first, from his onClick handler then the
Doesn't it have to load the model so that it knows what item it's talking to?

Yes - James is right here - it's a loadable detachable model - so it needs
to load the data in order to repopulate the list before deleting the item.
My guess is either you need to call the detach so that on the re-render it
gets reloaded, or you need to make sure your delete is being committed
Or, call detach(), then call modelChanged()?
