    When uploading a file via ice:inputFile, a component is nul

    Jens Weintraut Apprentice

      Hi,

      I don't know, if it's a Seam issue or an ICEfaces issue. So I'll ask both of you ;). Before I forget it: I'm using Seam 1.2.1.GA, ICEfaces 1.6 on a JBoss AS 4.0.5.GA.

      I've a page where an ice:inputFile is in an ice:popupPanel.

      <ice:panelPopup draggable="true"
       rendered="#{testactionDeveloper.showUpDownloadDialog}"
       visible="#{testactionDeveloper.showUpDownloadDialog}">
       <f:facet name="header">
       ... omitted ...
       </f:facet>
      
       <f:facet name="body">
       <ice:panelGrid columns="1" cellpadding="0" cellspacing="0" border="0">
       <h:dataTable value="#{testactionDeveloper.attachedFiles}"
       var="attachedFile"
       rendered="#{!empty testactionDeveloper.attachedFiles}">
       ... omitted ...
       </h:dataTable>
       <ice:inputFile actionListener="#{testactionDeveloper.upload}" style="margin-top: 30px;" id="upload" />
       </ice:panelGrid>
       </f:facet>
      </ice:panelPopup>


      The "testactionDeveloper" is a Seam component which is defined as follows:
      @Stateful
      @Scope(ScopeType.SESSION)
      @LoggedIn
      @Name("testactionDeveloper")
      public class TestactionDeveloperAction extends TestactionHandling implements TestactionDeveloper, Serializable {
       @In(required=false)
       private Release selectedRelease;
      
       @In(required=false)
       private Priorityclass selectedPriority;
      
       @In(required=false)
       private Severityclass selectedSeverity;
      
       @In(required=false)
       private User selectedUser;
      
       ... omitted, you'll see why ;) ...
      }


      As you can see TestactionDeveloperAction subclasses TestactionHandling:
      public class TestactionHandling {
       @PersistenceContext(unitName = "aresDatabase")
       protected transient EntityManager em;
      
       @In
       protected transient FacesContext facesContext;
      
       @In
       protected transient UpDownload upDownload;
      
       @In @Valid
       protected User user;
      
       public String upload(ActionEvent event) {
       InputFile uploadedFile = (InputFile) event.getSource();
       boolean success = false;
       if(uploadedFile.getStatus() == InputFile.SAVED) {
       if(testaction == null) {
       testaction = testactions.get(testactionIndex);
       }
       UpDownloadFileinfo fileInfo = new UpDownloadFileinfo();
       fileInfo.setName(uploadedFile.getFileInfo().getFileName());
       fileInfo.setFile(uploadedFile.getFile());
       fileInfo.setContentType(uploadedFile.getFileInfo().getContentType());
       fileInfo.setTestactionID(testaction.getID());
       success = upDownload.upload(fileInfo);
       }
       if( !success ) {
       return "failed";
       }
       return "uploaded";
       }
      
       public List<UpDownloadFileinfo> getAttachedFiles() {
       return upDownload.getAttachedFiles(testaction.getID());
       }
      
       ... omitted ...
      }


      Here you can see that upload() and getAttachedFiles() delegate to another Seam component. This component ("upDownload") is configured via components.xml and looks like this:
      @Scope(ScopeType.SESSION)
      @Stateful
      @LoggedIn
      public class UpDownloadDatabase implements UpDownload, Serializable {
       @PersistenceContext(unitName = "aresDatabase")
       private transient EntityManager em;
      
       @In
       private transient FacesContext facesContext;
      
       private boolean showUpDownloadDialog;
      
       public boolean upload(UpDownloadFileinfo fileInfo) {
       com.idsscheer.ares.entities.File dbFile = new com.idsscheer.ares.entities.File();
       dbFile.setName(fileInfo.getName().replaceAll(" ", "_"));
       dbFile.setTActID(fileInfo.getTestactionID());
       dbFile.setContenttype(fileInfo.getContentType());
      
      
       ... get the data ...
      
       dbFile.setData(dataFromFile.toByteArray());
      
       em.persist(dbFile);
       em.flush();
       return true;
       }
      
       public List<UpDownloadFileinfo> getAttachedFiles(long testactionID) {
       List<File> files = EMHelper.execQuery(em, "from File where TACT_ID=" + testactionID + " order by NAME ASC");
       List<UpDownloadFileinfo> result = new ArrayList<UpDownloadFileinfo>(files.size());
      
       for(File file : files) {
       UpDownloadFileinfo fileInfo = new UpDownloadFileinfo();
       fileInfo.setContentType(file.getContenttype());
       fileInfo.setName(file.getName());
       fileInfo.setTestactionID(file.getTActID());
       result.add(fileInfo);
       }
      
       return result;
       }
      }


      This additional "upDownload" component is necessary since it should be possible to switch between saving files in a db or on a filesystem. So I just use the interface UpDownload in the clients and set the implementation in components.xml.

      But my problem is now that as soon as I click on "Upload" the attribute "user" in TestactionDeveloperAction (TestactionHandling) is null. Therefore a RequiredException is thrown. But this attribute shouldn't be null, it isn't involved in the upload process. I don't know, what's wrong.

      Perhaps you can read sth out of the stack trace:
      15:51:33,015 WARN [UploadServlet] File upload failed
