So I'm populating an item into the LV, which is gonna have a Remove
button, so when I'm add the AFB in the onsubmit I write to remove the
ListItem which I'm currently populating??
The LV looks like this
final ListView<IMAccount> listview = new ListView<IMAccount>("ims", new
PropertyModel(person, "ImAccounts")) {...}
I tried to remove the markup for the ListView, but didn't found a
working way:
- I tried:
person.getImAccounts().remove(acc); where acc = item.getModelObject();
If I do so, than one item is removing from the LV, but not the correct
one, remember I'm just removed an element from the list, I didn't
removed anything from the markup, but the listview's gonna have one less
line. Why? And why not the removed item is disappearing?
----
- I tried
item.setVisible(false);
but then I did not removed the item from the model, so it would send
incorrect datas. The markup now works as intended.
----
- I tried
item.setVisible(false); person.getImAccounts().remove(acc);
so both of them, than when I pressed the remove button, I successfully
removed from the markup two(!) items. Why?
----
- I tried
final ListView<IMAccount> curr = this; final List<IMAccount> model =
getModelObject();
and in the AFB:
curr.remove(item);
model.remove(acc);
person.setImAccounts(model);
It looks like this is deleting from the markup the last item, and the
correct ListItem's row is setted to defaults...
The only thing I don't get, that when I remove an item from the model,
than why a different row is gonna disappear from the markup...
//In these cases when I'm remove from the model an element in the markup
always the last row is disappearing...
Any help would be appreciated.
Thanks

if removeall() doesnt do what you want then you have to find the
specific listitem that represents your deleted row and remove just
that one.

I tried to do this:
ListView obj = (ListView) form.get("rowPanel:ims");
obj.removeAll();
But after that, the input is forgotten.
I tought, that if I enable the ReuseItems, than the list will remember the
contents, but when I call, the removeAll(), it's just forgots the input
values. It's like I just left the reuseItems on false.
How can I achieve, that the new values won't be forgotten when I remove one
item from the list?
Thanks

you have ot call removeall() on the listview, not on the button.

I tried this:
item.add(new AjaxFallbackButton("imRemove", PersonForm.this) {
@Override
public void onSubmit(AjaxRequestTarget target, Form<?>
form) {
person.getIMAccounts().remove(acc);
removeAll();
if (target != null) {
target.addComponent(rowPanel);
}
}
}.setDefaultFormProcessing(false));
but it's still not working, it looks like that on every single
imRemove#onSubmit in the list the last element will disappear. I have no
idea what's causing this behavior...

Because of this:
listview.setReuseItems(true);
You should do a
removeAll()
in your onSubmit() method when you change the model (the list in this
case).
