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
