[jboss-user] [JBoss Seam] - s:fileUpload and Tomahawk extensionfilter

[baz]

I do need some tomahawk components in my app(together with the required extension filter) What is the preferred configuration for this?
I am asking because i have a problem with this combination and s:fileUpload. I searched this forum and the jira for posts describing such an incombatibility (with no success).
Using Seam 1.2.0.Patch1

My problem is:
When i upload a file this leads to a little problem in the decode method from UIFileUpload

  |    private static final String TOMAHAWK_WRAPPER_CLASS = "org.apache.myfaces.webapp.filter.MultipartRequestWrapper";
  | 
  |    public void decode(FacesContext context)
  |    {
  |       super.decode(context);
  |       
  |       Object request = context.getExternalContext().getRequest();
  |       
  |       if (!(request instanceof MultipartRequest) && 
  |                request instanceof HttpServletRequestWrapper)
  |       {
  |          request = ((HttpServletRequestWrapper) request).getRequest();
  |       }
  |       
  |       if (!(request instanceof MultipartRequest) &&
  |                request.getClass().getName().equals(TOMAHAWK_WRAPPER_CLASS))
  |       {
  | 
I have debugged this and
the request that comes in is a MultipartRequestWrapper but also 'request instanceof HttpServletRequestWrapper' yields true.
So the if statements have to be swapped . If not, a MultipartRequestWrapper will not be handled properly.

My question: Is this because i have a configuration error in my web.xml or is this a real problem (and possible fixed)?
Ciao,
Carsten
BTW
My Web.xml declares the extension filter before seam filter.
