        <center><p:commandButton value="Add Employee" action="insertemployee" id="insertemployee" style="margin-left:250px;"/></center>
    </div>

主flow.xml

             <view-state id="addEmployee">
<on-entry>
<evaluate expression="leaveBo.getallUser()" result="viewScope.allUser"></evaluate>
</on-entry>
    <transition on="insertemployee" to="addEmployeeInfo"></transition>

</view-state>

    <action-state id="addEmployeeInfo">
    <evaluate
        expression="leaveBo.insertEmpolyee(userInfo.fname,userInfo.lname,userInfo.emailId,userInfo.manager,userInfo.loginperson,userInfo.username,userInfo.password)"></evaluate>
    <transition to="addEmployee"></transition>
</action-state>

此处输入数据后，它将被保存，一旦保存，它将转换到同一页面。问题是我输入的值未被清除。

Answer 1

您有使用value="#{userInfo.username}"等属性定义的输入字段，因此我想您必须明确清除userInfo或其属性为空白？

或者仅为该一个页面/视图定义“本地”模型bean。虽然我承认从未做过JSF，所以我不知道WebFlow与JSF的确切结合。
