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>
| </component>
|
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>
| </redirect>
| </exception>
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

|
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:
http://jira.jboss.com/jira/browse/JBSEAM-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.
thanks
Nathan
