Channa Gunawardena commented on MASHUP-968:
-------------------------------------------
With the check for null and empty user ID's in place, in basic testing with a
null userId or userRegistry instance caused an error message which prompts the
user to 'try going back to the home page and starting over.' At this point the
standard session handling mechanism is able to handle this. Deferred for
further developer testing to verify in all scenarios.
> Exception when navigating to mashup.jsp page (or others) after hours of idle.
