Hi,
perhaps there is somebody in this forum who can help with this problem. So I just post my recent insights.
Judy recommended to avoid ice:popupPanel and to introduce a manager which should take care of a bean representing the file to upload. I tried this but the problem is still there. So here's what I posted in the mentioned ICEfaces forum posting:
Erm, I think I have to take back the multiple
when I'm talking about the up-/download functionality I want to implement.
Thanks for your hints. I took all your hints, but still I got this could not find stateful bean
exception. But this time I had a look to JBoss AS's server.log:

extends a class which implements general functionality for this and other similar managers. Here's the superclass (I skipped some methods and attributes):

protected transient EntityManager em;

protected transient FacesContext facesContext;
@In
protected IUpDownloadService upDownload;

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());

}

return upDownload.getCountOfAttachedFiles(testaction.getID());

this.showUpDownloadDialog = showProtocolDialog;
}
@SuppressWarnings("unused")
public void showUpDownloadDialog(ActionEvent event) {
showUpDownloadDialog = true;

@SuppressWarnings("unused")

public UpDownloadFileinfo getFileUpload() {
if(fileUpload == null) {
fileUpload = new UpDownloadFileinfo(testaction, testactions, testactionIndex, upDownload);
}
return fileUpload;
}
public void setFileUpload(UpDownloadFileinfo fileUpload) {
this.fileUpload = fileUpload;
}
}Here's the testactionDeveloper
subclass (it doesn't redefine its superclass methods):
@Stateful
@Scope(ScopeType.SESSION)
@Name("testactionDeveloper")
public class TestactionDeveloperAction extends TestactionHandling implements TestactionDeveloper, Serializable {
//nothing of interest here
}The UpDownloadFileinfo
is used for data transfer. That means it represents a file when uploading or downloading a file. The @Name annotation, the additional constructor and the upload method are implemented because it's done similar in the example you mentioned. In the first version this class was a plain getter/setter class.
@Name("fileUpload")
public class UpDownloadFileinfo implements IUpDownloadFileinfo {
private String name;
private File file;
private String contentType;
private long testactionID;
private long dbFileID;
private Testaction testaction;
private List<Testaction> testactions;
private int testactionIndex;
@In
private IUpDownloadService upDownload;
public UpDownloadFileinfo() {
}
public UpDownloadFileinfo(Testaction testaction, List<Testaction> testactions, int testactionIndex, IUpDownloadService upDownload) {
this.testaction = testaction;
this.testactions = testactions;
this.testactionIndex = testactionIndex;
this.upDownload = upDownload;
}
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);
}
setName(uploadedFile.getFileInfo().getFileName());
setFile(uploadedFile.getFile());
setContentType(uploadedFile.getFileInfo().getContentType());
setTestactionID(testaction.getID());
success = upDownload.upload(this);
}
if( !success ) {
return "failed";
}
return null;
}
}As you can see from the code above I added this addtional constructor which takes four parameters. It was necessary to do this because Seam destroyed its contexts before the upload method was invoked, what caused a NPE.
Just to make it clearer for me (and maybe for you): The upload before and after those changes worked fine. A file was received and saved. After the upload finished the page refreshed and displayed the new file in a list of available files. But when I click any button I'm getting this exception. It happens in the RESTORE_VIEW phase and it seems that the JTA transaction can't be restored (whatever this JTA transaction is good for).
I don't know why this happens, but I thought it would be a good idea to test Seam's file upload component. But it can't work with ICEfaces since the upload component expects a MultipartRequest
in the responsible servlet but it gets an com.icesoft.faces.webapp.http.servlet.ServletExternalContext.
I hope this information helps you in solving this problem.
Thanks in advance
Jens
