A "final page URL" can be set when publishing an assessment. When a student takes the assessment and submits their answers for grading, they will see a link on the confirmation page to the final page URL.
This URL displays correctly in both assessment settings and on the confirmation page in delivery - but when you click on it, the Sakai PID is appended to the URL.
Example: Set "http://www.google.com" as the final page url.
When the student clicks on it, they'll go to:
and get a 404 error.
This does not happen in the standalone 1.5 version of Samigo. It does happen on both the integrated 1.5 version on aam-dev, and the sakai-stable.mit.edu 1.5.0 version. (The 1.5.1m build isn't yet available.)
