When uploading a file via ice:inputFile, a component is nul
newlukai Aug 7, 2007 10:16 AMHi,
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:
