Re: How to delete an item from List view.
Hi Johan,
Yes that will be quickest solution ,
But this will clear the fields of all vehicles.

Johan Compagner wrote:
wasn't the quickest solution:
public void onSubmit() {
List vehicles = (List) getParent().getParent().getModelObject();
vehicles.remove(index);
listView.removeAll();
}
Then if the list itself is stable on the server side (if other persons can
also delete or add stuff to that list you really should do it differently)
that should work fine. After you alter the listviews model you have to
remove all the items so that it will rebuild

Hi Eelco,
RefreshingView is available in wicket 1.3.0.
While I'm using wicket 1.2.6.

Instead of using ListView, you could consider RefreshingView with it's
itemReuseStrategy set to ReuseIfModelsEqualStrategy.

Re: How to delete an item from List view.
Hi Igor,
Finally I'm able to find out the exact issue.
suppose There are 3 items in the list-
wicket will assign id as 0, 1 2. to those items.
So When we say item.getparent().remove(item) to item with id=1,
them It'll remove that item from list but item with id=2 will not remain as
it is..
i.e. Now list will have 2 items one with id=0 id=2.
So when we display list, it'll clears the fields for item with id=1.
so we need to update id field of item object... But think there is no way to
do that...
is there...???

My new code is -

vehicles.setOutputMarkupId(true);
vehicles.setItemReuseStrategy(new ReuseIfModelsEqualStrategy());
add(vehicles);
private static class VehiclesList extends RefreshingView {

super (id,model);
}
/**

{

models.add(new Model( (Vehicle)
((List)getModelObject()).get(i)));
}
return models.iterator();

Hi igor,
Ya I read this from one of ur doc.

I have implemented equals/hashcode in Vehicle object.
