since you are using a button the listview has to be inside a form
also,
Button bb = new Button(DEL) {
public void onSubmit() {
super.onSubmit();
// this is wrong, you should remove the item from the list
and let the listview refresh rather then removing the wicket component
- when listview redraws the item will be recreated...
listviewlist.remove(custel); <== make sure your
equals/hashcode is properly implemented
}
};
bb.setdefaultformprocessing(false); <== you dont want validation,etc.
item.add(bb);
try the changes above and i suggest you read the wiki page on models...
