Hi I posted this question on Stackoverflow, I'd like to do the same here as
well now:
I have a way to add panels in a listview. Each panel is associated with an
Object of type Type. I have an 'add' and an some 'remove' AjaxSubmitLinks.
Both have setDefaultFormProcessing(false) because I want non-submitted /
validated values to remain when someone add or removes an element.
setReuseItems(true) is set for the ListView. Please see the code snippet
below.
ListView itemContainer = new ListView<Type>("list", getList()) {
@Override
protected void populateItem(final ListItem<Type> listItem) {
final Component element =
createComponent(listItem.getModel());
listItem.add(element);
listItem.add(new AjaxSubmitLink("remove") {
@Override
protected void onSubmit(AjaxRequestTarget target,
Form<?> form) {
getList().remove(listItem.getIndex());
target.add(wrapper);
}
}.setDefaultFormProcessing(false));
}
};
itemContainer.setReuseItems(true);
add(itemContainer);
add(new AjaxSubmitLink("add") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form)
{
Type object = addObject();
getList().add(object);
target.add(wrapper);
}
@Override
public boolean isVisible() {
return getList().size() < DSAddableField.this.max &&
isEditable();
}
}.setDefaultFormProcessing(false));
Where wrapper contains everything, so everything is reloaded with Ajax. All
works well, expcet no matter which remove link I click the last element is
being removed. equals() method is overriden on Type based on a UUID check. I
did a debug and it would seem to me that the right element is removed from
the ListModel, but wrong values are sent down by the ajax response.
How can I get this to work? I tried to remove setReuseItem(true), but than
the non-saved values for list items were not reloaded. (Panels contain lot
of input fields)
Any suggestions?
UPDATE:
I already tried to remove the object with
getList().remove(listItem.getModelObject()), this was second solution but
still failed.
Regardless if I use remove by index or by modelobject the right element is
being removed from the list when using debugger.
UDAPTE 2:
If I remove "final int index = listItem.getIndex();" the right element is
removed opposed to the last one but when I add a new one to the list non
saved inputs are cleared which is the original problem I'm trying to solve.
Please advise.
