无法将 <p:ajax> 附加到非 ClientBehaviorHolder 父级

Question

我正在尝试调用一个函数来从下拉列表中选择一个值。这是我的代码：

<h:form id="frmUpload" enctype="multipart/form-data">  

       <p:column><h:outputText value="Select Team: " /></p:column>
        <p:column>
                #{' '}
                <h:selectOneMenu required="true" id="ddlTeam" value="#{telesalesUpload.selectTeam}">
                <f:selectItem itemValue="0" itemLabel="Dunning Team" />
                <f:selectItem itemValue="1" itemLabel="SAVD Team"  />
                </h:selectOneMenu>
                #{' '}
         <p:ajax process="@this" event="change" listener="#{telesalesUpload.UpdateTeam}" /> 

        </p:column>

<h:outputText value="Note: first row will be skipped as header row!" />  
<p:fileUpload  fileUploadListener="#{telesalesUpload.handleFileUpload}"  
        process = "ddlTeam" 
        auto="true"
        mode="advanced"
        update="messages,:frmData"  
        allowTypes="/(\.|\/)(csv|jpe?g|png)$/"/>  
<p:growl id="messages" showDetail="true"/>

但我收到此错误：无法附加到非 ClientBehaviorHolder 父级

你必须把<p:ajax>放在<p:selectOneMenu>里面。

<p:column>
     #{' '}
     <p:selectOneMenu required="true" id="ddlTeam" value="#{telesalesUpload.selectTeam}">
         <f:selectItem itemValue="0" itemLabel="Dunning Team" />
         <f:selectItem itemValue="1" itemLabel="SAVD Team"  />
         <p:ajax process="@this" event="change" listener="#{telesalesUpload.UpdateTeam}" /> 
     </p:selectOneMenu>
     #{' '}
</p:column>
