Update:
When setting #setAllowDefault(false), the #onevent method of the web markup
container is called, but in addition also the #on select method of sortable.
When setting #setAllowDefault(true), the #onevent method is not called at all,
only the #on select method.
It seems that setAllowDefault(false or true) does not prevent the event
bubbling to parents. What might be missing?
@Override
protected void populateItem(ListItem<String> item) {
...
WebMarkupContainer infoLink = new WebMarkupContainer("infoLink");
infoLink.add(new AjaxEventBehavior("onclick") {
@Override
protected void onEvent(AjaxRequestTarget target) {
}
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes
attributes) {
super.updateAjaxAttributes(attributes);
attributes.setAllowDefault(false);
}
});
@Override
public void onSelect(AjaxRequestTarget target, List<String> items) {
