[Tobago] NotSerializableException in file uplaod

[H. Swaczinna]

Hi,

I want to do a file uplaod with Tobago, but I always get an exception
when submitting the page:

2007-01-23 15:40:44 http-8080-Processor23 ERROR - 
org.apache.myfaces.application.jsp.JspStateManagerImpl:599 - Exiting s
erializeView - Could not serialize state: 
org.apache.commons.fileupload.DeferredFileOutputStream
java.io.NotSerializableException: 
org.apache.commons.fileupload.DeferredFileOutputStream
        at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1081)
        at 
java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1375)
        at 
java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1347)
...

JSP:

<tc:file id="dateiname" value="#{anlagenController.file}"/>

AnlagenController.java:

  public void setFile(FileItem file) {
    LOG.error("Setting fileItem " + file.getName());
    this.filename = file.getName();
  }

web.xml:

  <filter>
    <filter-name>multipartFormdataFilter</filter-name>
    
<filter-class>org.apache.myfaces.tobago.webapp.TobagoMultipartFormdataFilter</filter-class>
  </filter>

classpath:

tobago-fileupload-1.0.10-SNAPSHOT.jar
commons-fileupload-1.0.jar


I've no idea what's wrong or missing. And there's no documentation,
except the simple example in the source...

Regards
Helmut
