[jboss-user] [JBoss Seam] - 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>
