optiontransfers选择将值从一个列表传输到另一个列表

Question

我试图在Struts2 + Hibernate中使用optiontransferselect将值从一个列表传输到另一个列表并将其保存到数据库中。

<s:form name="frmIssueSerialDetails" action="SaveIssueSerialDetails" >    
<s:optiontransferselect  name="esr.stdId"
                         listKey="stdId" 
                         listValue = "stStockSerialNo"
                         leftTitle = "Available Serial No:"
                         rightTitle = "Selected Serial No:"
                         list = "listStockRecSerialNoLeft"
                         multiple = "true"
                         doubleMultiple="true"
                         headerKey = "-1"
                         headerValue = "-- Serial Numbers --"
                         doubleList = "listStockRecSerialNoRight"
                         doubleName = "eisd.erpmStockReceived.stId"
                         doubleListKey = "erpmStockReceived.stId"
                         doubleListValue = "stStockSerialNo"
                         doubleHeaderKey = "-1"
                         doubleHeaderValue="-- Serial Numbers --"
                         cssClass="queryInput"
                         doubleCssClass="queryInput"
                         doubleId="right" />
<s:submit value="Save Issue Serial No" />
</s:form>

listStockRecSerialNoLeft填充得很好，但我无法将值从listStockRecSerialNoLeft转移到listStockRecSerialNoRight。我还想将传输的值从listStockRecSerialNoRight保存到数据库。                         但 当我删除listKey后，我就可以将值从listStockRecSerialNoLeft移到listStockRecSerialNoLeftRight
