s:fileupload control problem with Ajax

[lkw]

Hi,

I get a NullPointerException when submitting a form that contains s:uploadfile control in Seam 1.2.1GA. Refer code below.

I can submit the form successfully using the JSF commandButton control. However, when I click on the Ajax4Jsf commandButton, JBoss give a NullPointerException. Has anyone encounter the same problem?

Thanks.

<h:form enctype="multipart/form-data">
 <div class="prop">
 <div class="rectangle">
 <table width="100%" cellspacing="1" cellpadding="1" border="1">
 <tr>
 <td>
 <div class="valueInline">
 <h:inputText value="#{entityBean.primaryName}" size="40" />
 </div>
 </td>
 </tr>
 <tr>
 <td colspan="3">
 <div class="name">
 <h:outputLabel for="pictureLogo">Logo</h:outputLabel>
 </div>
 <div class="valueInline">
 <s:fileUpload id="pictureLogo" data="#{entityBean.logo}" size="80" />
 </div>
 </td>
 </tr>
 </table>
 </div>
 <div>
 <a:commandButton value="Save" action="#{restaurantWorker.addRestaurant}" />
 <h:commandButton value="Save" action="#{restaurantWorker.addRestaurant}" />
 </div>
</h:form>

File upload with Ajax doesn't work, due to some limitations of browsers and Ajax. To workarround I' ve used a hidden IFRAME with Javascript to post the file.
