    MultipartFilter - exception redirect missed when maxsize exc

    Nathan Wray Newbie

      Hi, I'm using the file upload tag s:fileUpload and org.jboss.seam.web.MultipartFilter in a seam 2.0.0CR1 project. I have a maxRequestSize configured in components.xml:

       <component class="org.jboss.seam.web.MultipartFilter">
       <property name="createTempFiles">false</property>
       <property name="maxRequestSize">41943040</property>

      and in pages.xml I have the following:

      <exception class="org.jboss.seam.web.FileUploadException">
       <redirect view-id="/main.xhtml">
       <message severity="error">File upload failed, probably because the file is too large</message>

      When I upload a file larger than the max size, I see a debug page with the following stack trace:

      2007-09-28 10:24:40,703 ERROR [org.jboss.seam.web.ExceptionFilter] handling uncaught exception
      org.jboss.seam.web.FileUploadException: Multipart request is larger than allowed size

      at org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:44)

      rather than seeing main.seam with the expected message, as configured in pages.xml. Following the stack trace back it seems that ExceptionFilter at line 93 assumes a Manager will be found in the request. When the Manager comes back null we get the NPE. I created a patch I'm using locally that handles the missing Manager, attached to Jira 1995:


      Am I seeing this due to some underlying misconfiguration on my side or is this a bug? I created the Jira last week but no feedback as of yet.
