The optional annotation's element is a String for command's name and that name is referenced in a ZUL with event-command binding. If it's not provided, the method name is set as the command name by default.

public void search(){
items = new ListModelList<Item>();
items.addAll(getSearchService().search(filter));

public void deleteOrder(){
getService().delete(selected); //delete selected
getOrders().remove(selected);

}
