多个命令按钮操作不能在jsf中的同一页面中以相同形式在不同的字段集中工作

Question

我试过保持eah fieldset的不同形式，并通过保持不同的面板和删除fieldset尝试它，但我不能让按钮工作。而且如果我在下面发布的代码中删除第三个字段集，则另外两个字段集正在运行。

<h:form styleClass="pageContainer" xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:p="http://primefaces.org/ui"
    xmlns:f="http://java.sun.com/jsf/core"  id="form22">
    <p:toolbar styleClass="toolBar">
        <p:toolbarGroup align="right">
        </p:toolbarGroup> 
    </p:toolbar>

    <h:form prependId="false">
    <p:fieldset legend="Change Name">
        <h:panelGrid styleClass="registration_form">
            <h:panelGrid columns="3" id="name_form1" >

            <h:outputText value="Name"/>
                <p:inputText value="#{userMB.user.name}" id="name"
                    style="width:250px; margin-left:58px;" required="true" label="Job Title">
                    <f:validateLength minimum="5" maximum="50"></f:validateLength>
                </p:inputText>
                <p:commandButton id="reportButton1" styleClass="update" value="Update" action="#{adminMB.updateUserName}" update=":form22" />


                </h:panelGrid>
                </h:panelGrid>
                </p:fieldset>

     <p:fieldset legend="Change Password">
        <h:panelGrid styleClass="registration_form">
            <h:panelGrid columns="2" >

            <h:outputLabel for="oldPassword" value="Old Password:" />
            <p:password value="#{adminMB.password}" id="oldPassword" style="width:250px"  label="Old Password"/>

            <h:outputLabel for="NewPassword" value="New Password:" />  
            <p:password id="NewPassword" value="#{adminMB.newpassword}" match="ConfirmPassword" label="NewPassword"  style="width:250px"/>  

            <h:outputLabel for="ConfirmPassword" value="Confirm Password:" />  
            <p:password id="ConfirmPassword" value="#{adminMB.newpassword}" label="ConfirmPassword"  style="width:250px"/>

                <p:commandButton  id="reportButton2" styleClass="update" value="Update" action="#{adminMB.updateUser()}" update=":form22" /> 
                </h:panelGrid>
                </h:panelGrid>
                </p:fieldset>


    <p:fieldset legend="Signature">
        <h:panelGrid styleClass="registration_form">
            <h:panelGrid columns="3" >

             controls="bold italic underline font color highlight bullets numbering outdent indent rule pastetext"
              value="#{adminMB.signaturemsg}" 
              label="Question" required="true" > </p:editor>

                <p:commandButton id="reportButton3" styleClass="update" value="Update"  action="#{adminMB.updateUserName()}"/>

                </h:panelGrid>
                </h:panelGrid>
                </p:fieldset> 

    <p:growl id="message"  />
</h:form>
</h:form>
