Ajax form submission issue with struts 2 file tag

[sayan mandal]

Hi All,

   I would appreciate your IMMEDIATE help on this.

   Ajax form submission does NOT occur if it contains a struts2-file tag
(the form gets submitted and expected content correctly shows up in the
target div IFF the file tag is removed). Code snippet below (struts
2.1.8,struts2-dojo-plugin-2.1.6.jar).

----------------------------
    <s:form theme="simple" method="post" id="f2"
enctype="multipart/form-data" >
        <table>
            <tr>
                <td>
                    <s:select name="dummyDay" list="%{DummyDays}"
cssClass="tdfont"
onchange="javascript:dojo.event.topic.publish('showVendorDetail')" />
                </td>
                <td>
                    <s:file id="xx" name="yy" cssClass="tdfont" />
                </td>
            </tr>
        </table>
    <s:url id="d_url" action="loadvndrwebsite" />
    <sx:div id="vendorDetails" href="%{d_url}" autoStart="false"
listenTopics="showVendorDetail" updateFreq="100"  highlightColor="#ddaaba"
formId="f2">
    </sx:div>
    </s:form>
----------------------------

Thanks much,
Sayan
