I fixed the problem. For the record, to help someone else making the same upgrade, I needed to update the package name for the TapestryFilter in the web.xml

Hi All, I just upgraded from 5.0.11 to 5.0.13. After fixing compile errors (changing package names from com.apache.tapestry to com.apache.tapstry5) and running my app, I get an exception with the message "No root element has been defined.". Is there something that changed between 11 and 13 to cause this to happen? Thanks!
