[JBoss Seam] - s:fileupload control problem with Ajax
by 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>
