小编tho*_*.st的帖子

我想在选择第一个SelectOnMenu的任何项目时更新第二个SelectOneMenu.就像现在一样,我从ManagedBean获取SelectOneMenus的值.我想我将使用AJAX(jquery)将参数发送到ManagedBean.

<h:form>
    <div class="center">
        <h:panelGrid id="editTable" columns="2" styleClass="center">
            ...
            <h:outputText value="#{msg.timetable_list_category}" />
            <h:selectOneMenu class="category">
                <f:selectItems value="#{categoryBackingBean.categorys}" var="c"
                    itemLabel="#{c.category_Name}" itemValue="#{c.id}" />
            </h:selectOneMenu>

                <h:outputText value="#{msg.timetable_list_seminarblock}" />
            <h:selectOneMenu class="seminarblock">
                <f:selectItems value="#{seminarblockBackingBean.seminarblocks}" var="s"
                    itemLabel="#{s.seminarblock_Name}" itemValue="#{s.seminarblock_Id}" />
            </h:selectOneMenu>
            ...
        </h:panelGrid>
        ...
    </div>
</h:form>

总是当我部署我的项目(jsf)时,我在JBoss AS7上遇到以下错误.在JBoss 6上一切正常.该错误消息的原因是什么？你知道我怎么解决这个问题吗？
