org.apache.el.parser.ParseException： 遇到" <ILLEGAL_CHARACTER> JSF+Richfaces Error

Question

下面显示了我在JSF+Spring项目中的代码。请帮我解决这个问题

感谢这是我的JSF代码在XHTML文件

我尝试了@form/@this也。但是同样的结果

错误是输入文本没有提交到控制器

<a4j:region id="panel-region">
    <f:facet name="header">
        <h:outputText value="SAM Selector"/>
    </f:facet>
    <rich:panel style="clear:both;" header="Search SAM" styleClass="col" id="panelSamSearch">
        <ui:decorate template="/jsf/templates/two_columns.xhtml">
            <ui:define name="left_label">*Search By</ui:define>
            <ui:define name="left_field">
                <h:selectOneMenu value="#{pOSController.samType}" id="samType">
                    <f:selectItem itemValue="a" itemLabel=""/>
                    <f:selectItem itemValue="samUid" itemLabel="SAM UID"/>
                    <f:selectItem itemValue="samDid" itemLabel="SAM DID"/>
                    <f:selectItem itemValue="status" itemLabel="Status"/>
                </h:selectOneMenu>
            </ui:define>
            <ui:define name="right_label">
                <h:inputText value="#{pOSController.samValue}" id="samValue"/>
            </ui:define>
            <ui:define name="right_field">
                <a4j:commandButton id="samBtnSearch" value="Search" execute="lp"
                                   action="#{pOSController.loadSamPosTagging(rich:element('samType').value,rich:element('samValue').value)}"
                                   render="#{rich:clientId('dataTableSamView')}"/>
            </ui:define>
        </ui:decorate>
    </rich:panel>

这里显示了我的错误

i added

<a4j:commandButton id="samBtnSearch" value="Search" execute="lp" action="#{pOSController.loadSamPosTagging(rich:component('samType'),rich:component('samValue'))}" render="#{rich:clientId('dataTableSamView')}"  />

则字符串如下所示。它没有传递字段的值。只是我传递返回的名称:-)document.getElementById('frmMasPosTagging:dataTablePosView:0:samType')

Answer 1

换行

action="{pOSController.loadSamPosTagging(rich:element('samType').value,rich:element('samValue').value)}"

action="{pOSController.loadSamPosTagging()}值"samType"one_answers"samValue"可以在控制器中访问，因为它们被映射到支持bean，并且支持bean将被更新。所以不需要从UI发送值我假设pOSController有'samType'和'samValue'的getter和setter
