Action not invoked - config error?

[taprogge]

Hello all!

I am currently working on a project that has been dorment for a while. It uses JBoss Seam with JBoss Portal through the MyFacesGenericPortlet.

A have updated Seam to 1.2.1 now and added a new component to test the s:fileUpload functionality.

My problem is now that the action declared in my jsp's commandButton is never invoked when I click it. The server just redisplays the portal page. No error message is given.
The component itself is found when the application deploys, that was ther first thing I checked.
This obviously has to be an error on my part, but somehow, it eludes me.
Perhaps anyone of you has some insights?

My jsp looks like this:

<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%@ taglib uri="http://jboss.com/products/seam/taglib" prefix="s"%>

<f:view>
 <h3>Upload</h3>
 <p>
 <h:form enctype="multipart/form-data">
 <s:fileUpload data="thedatafield"/>
 <h:messages style="color:red"/>
 <h:commandButton type="submit" value="upload" action="#{UploadAction.load}" styleClass="portlet-form-button" />
 </h:form>
 </p>
</f:view>

and my component like this (I'll omit the local interface and omit imports... nothing fancy in there):

@Stateful
@Scope(SESSION)
@Name("UploadAction")
public class UploadActionBean implements UploadAction {

 private static Logger logger = Logger.getLogger(UploadActionBean.class);

 @PersistenceContext(type = EXTENDED)
 private EntityManager em;

 @In(create = true)
 @Out(required = false)
 private byte[] thedatafield;

 @In(create = true)
 private transient ResourceBundle resourceBundle;

 @In
 private transient FacesContext facesContext;

 @SuppressWarnings("unchecked")
 public String load() {
 System.out.println("in load()");
 if (thedatafield != null) {
 logger.info(thedatafield);
 }
 else {
 logger.info("thedatafield is null");
 }
 return Outcome.REDISPLAY;
 }

 public void setThedatafield(byte[] field) {
 this.thedatafield = field;
 }

 public byte[] getThedatafield() {
 return this.thedatafield;
 }

 @Remove
 @Destroy
 public void destroy() {
 // nothing to clean up here
 }
}

Thanks in advance for any ideas you guys might have.

Best regards,

Phil
