Hi,
here some example code for refreshing a listView via an AjaxButton if I
understood you right. Perhaps it will help you.
Things to note:
- add the WebMarkupContainer to the AjaxRequestTarget (target.add(..)) not the
ListView itself because this will not work. You tried something like that in
your example code.
public class TestPage extends WebPage {
@Override
protected void onInitialize() {
super.onInitialize();
final List<String> pieces = new ArrayList<>();
final WebMarkupContainer listViewContainer = new
WebMarkupContainer("listViewContainer");
listViewContainer.setOutputMarkupId(true);
listViewContainer.add(new ListView<String>("listView",
Model.ofList(pieces)) {
@Override
protected void populateItem(ListItem<String> item) {
item.add(new Label("rowItem", item.getModel()));
}
});
add(listViewContainer);
final Form<Void> form = new Form<>("testForm");
add(form);
form.add(new AjaxButton("refreshBtn") {
int count = 0;
@Override
protected void onSubmit(AjaxRequestTarget target) {
super.onSubmit(target);
// click adds a new rowItem
pieces.add("Row Item String " + count);
count++;
target.add(listViewContainer); // refresh the surrounding div
container
}
});
}
}
