There is a JSF 2.3 incompatibility with rich:inputFile because it does not prepend the portlet namespace to request parameters.
Steps to Reproduce:
1. Deploy the richfaces-applicant-portlet to Pluto 3.0
2. Add the portlet to a Pluto portal page named "richfaces-applicant"
3. Visit the Pluto portal page:
4. Try to upload a file
The file uploads correctly and appears in the list of uploaded files.
The file does not upload and a "server error" is reported near the file upload component in the portal page.
