我试图使用jsf中的Request Scoped JSF Managed Bean GendersManager.java在xhtml页面之间传递值，如下所示：
页面流：
index.xhtml ---超级链接---> GendersInsertCreateKeyin.xhtml --- Confirm ---> GendersInsertCreateConfirm.xhtml --- Commit ---> GendersInsertCreateCommitted.xhtml --- Committed --->索引。 xhtml
问题：
字段值显示在“ GendersInsertCreateConfirm.xhtml”中（即在第一次导航期间） ，但是字段值在GendersInsertCreateCommitted.xhtml中（即在第二次导航期间）变为空/空字符串。
更新：
a）将GendersInsertCreateConfirm.xhtml中的用户界面 h：outputText 转换为 h：inputText ，以在页面流期间保留字段值。
b）转换用户界面后，将 h：outputText 更改为 h：inputText 并设置其参数 readonly = true < / strong>，则页面流期间字段值将变为空/空字符串。
c）尝试使用GendersInsertCreateConfirm.xhtml中的以下javascript代码将值设置为jsf受管beanGendersManager的成员变量：
<h:commandButton id="insertCreateConfirmBtnUi" value="Genders Insert Create Confirm" action="#{gendersManager.insertCreateConfirm}"/></td>
<f:verbatim>
<script type="text/js" language="javascript">
var genderSlNoUiText = document.getElementByid("genderSlNoUi").getValue();
</script>
<f:setPropertyActionListener target="#{gendersManager.genderSlNo}" value=genderSlNoUiText/>
<f:verbatim>
</h:commandButton>
，但引发错误，该值应带有引号
请指导我使用jsf托管bean在xhtml页面之间传递值。
