[Tomahawk] NullPointer Exception during File-Upload

[Wolfgang]

Hi,

I tried to upload a File but I always got a NullPointerException, 
because the uploadFile.getBytes(), uploadFile.getContentType() and
uploadFile.getName()) are null.
I don't understand why?!

Cheers!


private UploadedFile uploadFile;


public void upload(ActionEvent evt) throws IOException
   {
       FacesContext facesContext = FacesContext.getCurrentInstance();
       
facesContext.getExternalContext().getApplicationMap().put("fileupload_bytes", 
uploadFile.getBytes());
       
facesContext.getExternalContext().getApplicationMap().put("fileupload_type", 
uploadFile.getContentType());
       
facesContext.getExternalContext().getApplicationMap().put("fileupload_name", 
uploadFile.getName());
       
   }

// Getter and Setters

   public UploadedFile getUploadFile() {
       return uploadFile;
   }

   public void setUploadFile(UploadedFile uploadFile) {
       this.uploadFile = uploadFile;
   }


<t:inputFileUpload
                               id="myUploadedFile"
                               storage="file"
                               accept="image/*"
                               styleClass="myStyle"
                               value="#{home.uploadFile}"/>
                       
<h:commandButton actionListener="#{home.upload}"/>
