FileUpload ViewExpiredException PrimeFaces2.2.1

[johnpage09]

Dear All,
I am new PrimeFaces user and have been impressed with the features and the updates. Its a great product and a big thank you to all the contributors.
While most of the features I have implemented are working fine, I am getting an exception when I try to upload a file.
I am using MyFaces 2.0.4, PrimeFaces 2.2.1, Tomcat 7.0.22, Java 1.6, commons-fileupload 1.2.2, commons-io 1.4

The exception is as under.

I have a Filter Defined in the web.xml
<!-- Filter for File Upload (Prime Faces) -->

My upload component has been defined as follows:
<h:form id="uploadForm" enctype="multipart/form-data">
<h:panelGrid columns="1" rendered="#{loginBean.uploadSectionVisible}">
<p:fileUpload fileUploadListener="#{fileUploadBean.handleFileUpload}"
mode="advanced"
update="messages"
sizeLimit="100000"
allowTypes="/(\.|\/)(gif|jpe?g|png)$/"/>

<p:growl id="messages" showDetail="true"/>
</h:panelGrid>
</h:form>

My handleFileUpload method in the backing bean is defined as follows:
public void handleFileUpload(FileUploadEvent event) {

//Primitives
final int BUFFER_SIZE = 6124;
String folderToUpload;
// FacesContext context = FacesContext.getCurrentInstance();
// UploadedFile file = event.getFile();

System.out.println("File upload triggered!!");

ExternalContext extContext=FacesContext.getCurrentInstance().getExternalContext();

File result = new File(extContext.getRealPath("//WEB-INF//files//" +
event.getFile().getFileName()));
//System.out.println(extContext.getRealPath("//WEB-INF//files//" +
// event.getFile().getFileName()));

try {
FileOutputStream fileOutputStream = new FileOutputStream(result);

byte[] buffer = new byte[BUFFER_SIZE];

int bulk;
InputStream inputStream = event.getFile().getInputstream();
while (true) {
bulk = inputStream.read(buffer);
if (bulk < 0) {
break;
}
fileOutputStream.write(buffer, 0, bulk);
fileOutputStream.flush();
}

fileOutputStream.close();
inputStream.close();

FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName()
+ " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);

} catch (IOException e) {
e.printStackTrace();

FacesMessage error = new FacesMessage(FacesMessage.SEVERITY_ERROR,
"The files were not uploaded!", "");
FacesContext.getCurrentInstance().addMessage(null, error);
}


}

I have tried upgrading to PrimeFaces 3.0.M4 but that broke my Theme layout even though I upgraded to 1.0.2 and so I switched back to 2.2.1

I am not using any other Faces component as PrimeFaces has met all my requirements. If I can't fix this I might have to switch to Tomahawk.
Any help will be much appreciated.

Kind Regards,
John

We had the same problem - we fixed that wih switching to Mojarra and Server-Side-Viewstate.
But i would use MyFaces and upgrade to 3.0.M4!

Try new fileupload of 3.0.M4, much better than 2.2.

Thanks Catagay. I did try to upgrade by my view didn't render correctly even though I upgraded my Theme jar. I don't want to move from one problem to another.
Is there a known solution for the problem I am facing. It would be much appreciated.
By the way, I am using Chrome.

John

Thanks for the tip zoigl. My ViewExpiredException is now gone after I changed to server side saving so that's a step forward.

Zoigl. I have upgraded to 3.0.M4 and my view is rendering fine.When I click on the upload button, everything appears to go well
and there are no errors but I can't see the file on the WebServer.
Where should I be looking? I am running on Tomcat7.0.22
and here is the code of my bean method...

//Primitives
final int BUFFER_SIZE = 6124;

public void handleFileUpload(FileUploadEvent event) {
ExternalContext extContext=FacesContext.getCurrentInstance().getExternalContext();
FacesMessage msg = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
File result = new File(extContext.getRealPath("c:\\temp\\" +
event.getFile().getFileName()));
//System.out.println(extContext.getRealPath("//WEB-INF//files//" +
// event.getFile().getFileName()));

try {
FileOutputStream fileOutputStream = new FileOutputStream(result);

byte[] buffer = new byte[BUFFER_SIZE];

int bulk;
InputStream inputStream = event.getFile().getInputstream();
while (true) {
bulk = inputStream.read(buffer);
if (bulk < 0) {
break;
}
fileOutputStream.write(buffer, 0, bulk);
fileOutputStream.flush();
}

fileOutputStream.close();
inputStream.close();

FacesMessage message = new FacesMessage("Succesful", event.getFile().getFileName()
+ " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, message);

} catch (IOException e) {
e.printStackTrace();

FacesMessage error = new FacesMessage(FacesMessage.SEVERITY_ERROR,
"The files were not uploaded!", "");
FacesContext.getCurrentInstance().addMessage(null, error);

}

I think it's obvious that if I had found the solution there, I would not have asked.
