JSF选择一个菜单集错误

Question

我使用select one菜单从map<String,Integer>中选择，但它只选择0:

 <p:fieldset id="locations" legend="locations" toggleable="false">
        <p:selectOneMenu id="locations" value="#{bean.selectedLocation}" filter="true" filterMatchMode="contains">
            <f:selectItems value="#{bean.availableLocations}"/>
        </p:selectOneMenu>
    </p:fieldset>

和我的豆子是:

@ManagedBean
@ViewScoped
public class Bean  {
private Map<String, Integer> availableLocations = new HashMap<>();
private int                  selectedLocation   = 1;

public int getSelectedLocation() {
    return selectedLocation;
}
public void setSelectedLocation(int selectedLocation) {
    this.selectedLocation=selectedLocation;
}
@Override
protected void init() {
        availableLocations.clear();
        availableLocations.putAll(Locations.getLocations());
}

}

当我选择任何项目时，它只是将0设置为selectedLocation

当我将fieldset放入表单时它不会设置任何内容

我发现问题了

通过添加ajax，问题将解决

<p:ajax event="change" update="@this" />
