Ajax没有设置bean值并且达到了监听器

我在从SelectOneListbox更新图形图像时遇到问题。我想做的是，当用户在SelectOneListbox中选择一个项目时，我想在不同组件的页面上更新图像。

我正在尝试使用Ajax，但即使ajax请求离开Web浏览器，它也不会更新组件。它遍历所有阶段进入JSF阶段：RESTORE_VIEW 1 ... RENDER_RESPONSE 6 不幸的是，它并没有停留在监听器上，也没有将组件的值设置为实际值。 它正确到达转换器并进行转换，但就是这样。然后没有设置'editor'bean的属性。

这是更好想象的图像:)

当我在网络浏览器中收到回复时，它说：

<partial-response id="j_id1">
    <changes>
        <update id="j_id1:javax.faces.ViewState:0">2751554428361535891:1425762350197262148</update>
        <extension ln="primefaces" type="args">{"validationFailed":true}</extension>
    </changes>
</partial-response>

托管Bean 

@ViewScoped
@ManagedBean(name = "editor")
public class EditorView {

    @ManagedProperty(value = "#{localizationService}")
    private LocalizationService localizationService;
    private LangFlag selectedLanguage;

    public void languageUpdated(AjaxBehaviorEvent event){
        System.out.println(event);
    }

    public void setSelectedLanguage(LangFlag selectedLanguage) {}
    public String getSelectedLanguage{};
}

转换器（正确实施，请跳过此处）

@FacesConverter
public class LanguageConverter implements Converter, Serializable {

    @Override
    public Object getAsObject(FacesContext fc, UIComponent uic, String value) {}

    @Override
    public String getAsString(FacesContext fc, UIComponent uic, Object object) {}

}

edit.xhtml 

<h:panelGroup id="countrySelectFlagPanel">
    <h:form id="translation_editor">
        <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>
        <p:graphicImage id="chooseLangBtn" width="22px" height="22px"
    alt="#{t.lang.englishName}" 
    library="main" name="/images/flags/var/#{editor.selectedLanguage.country.alpha2}.svg"/>
        <p:overlayPanel id="langPanel" for="chooseLangBtn" 
    showCloseIcon="true" dismissable="true"
    widgetVar="langOverlayPanel">
            <p:selectOneListbox id="langSelect" value="#{editor.selectedLanguage}" converter="#{languageConverter}" 
            var="t" filter="true" filterMatchMode="startsWith" 
            onclick="PF('langOverlayPanel').hide(); alert($('#translation_editor\\:langSelect_input').val())"
            valueChangeListener="#{editor.languageUpdated}">
                <f:selectItems value="#{editor.langFlagMappings}" var="l10n" 
           itemLabel="#{l10n.lang.englishName} (#{l10n.lang.nativeName})" 
           itemValue="#{l10n}"/>
                <p:ajax process="@this" listener="#{editor.languageUpdated}"  />
                <p:column><h:graphicImage width="22px" alt="#{t.lang.englishName}" 
                      library="main" name="/images/flags/var/#{t.country.alpha2}.svg"/></p:column>
                <p:column><h:outputText value="#{t.lang.englishName}" /></p:column>
