Struts2-如何创建一个 <s:form> 对于中的每一行 <display:table>

Question

I was trying to show a displaytag table and I wish to map each row on a different s:form. Each row show all the attributes of my ComputerSystem object and I wish to choose one row and act on the related object. I tryed to put multiple display:column in one form, but when I load the JSP, I don't find any form tag in the generated source code.

(I have to use s:form because one of my columns contains as:doubleselect)

Any suggestion?

My code:

<display:table name="${systemList}" uid="row" pagesize="20" sort="list" requestURI="" >

<display:column title="System ID" property="systemID" />

            ... other columns ...

<s:form action="provision.action" method="post" name="provisionForm%{#attr.row.systemID}">

<display:column title="IP" >
    <s:textfield name="systemList[%{#attr.row_rowNum - 1}].ip"  />
</display:column>

<display:column>
    <s:submit type="image" src='image.png' name='submit' />
</display:column>
</s:form>

</display:table>

Thanks in advance

您可以在装饰器内部生成代码，获取行对象属性，然后在displaytag内使用装饰器。
