> Project: MyFaces Tomahawk
> Issue Type: Bug
> Components: ExtensionsFilter

> The getParameter*() methods of MultipartRequestWrapper don't work correctly
> in Tomcat 6/JSP 2.1(at least). I think the problem applies to parameters in
> an included file, but it may apply in other places, too. To reproduce the
> problem, create a jsp file that includes another jsp file and uses <jsp:param
> /> to pass a parameter to the included file. When the extension filter is
> "active" (i.e. a form with enctype=multipart/form-data" is submitted), the
> parameter will not be available in the included file.
> The problem is that MultipartRequestWrapper only parses the request once, so
> it doesn't pick up the new request parameters in the included file.
> I was able to fix the problem by modifying parseRequest() to only retrieve
> the FileItem parameters and then the getParameter*() methods to call through
> to the wrapped request getParameter*() as necessary.
> I don't know enough about all of this to know whether or not my fix is the
> right way to do it but I'll attach my version of MultipartRequestWrapper.java
