在使用springboot的vaadin流项目中，我遇到一个问题，即不能绑定带有组合框的枚举值。 我在下面提供了我的代码。有人可以帮我吗？
组合框实例化
private ComboBox<Country> nationality = new CompoBox<>("Nationality");
绑定代码：
binder.forField(nationality)
.bind(Coach::getNationality,Coach:setNationality);

我认为您错过了<!-- Map -->
<div id="map" style="width: 100%; height: 400px;"></div>
<input type="hidden" id="location" value="42.6903741,23.3122929" />
<!-- Script -->
<script type="text/javascript" src="https://maps.googleapis.com/maps/api/js?key=XXX&callback=initMap&language=en" async defer></script>
<script type="text/javascript">
function initMap() {
// Init location
var my_location = $("#location").val().split(",");
// Init position
var my_position = new google.maps.LatLng(my_location[0], my_location[1]);
// Init map
var my_map = new google.maps.Map(document.getElementById("map"), {
center: my_position,
zoom: 17
});
// Init marker
var my_marker = new google.maps.Marker({
position: my_position,
map: my_map,
draggable: true,
title: "Choose location..."
});
// Init listener
google.maps.event.addListener(my_marker, "dragend", function(event) {
$("#location").val(event.latLng.lat() + "," + event.latLng.lng());
});
// Init geolocation
if(navigator.geolocation) {
navigator.geolocation.getCurrentPosition(getLocation);
}
function getLocation(my_location) {
var my_position = new google.maps.LatLng(my_location.coords.latitude, my_location.coords.longitude);
my_marker.setPosition(my_position);
$("#location").val(my_location.coords.latitude + "," + my_location.coords.longitude);
}
}
</script>
电话。这是一个基于Project Base for Vaadin Flow
