[samigo-team] Request for code review

[David Horwitz]

Hi Gang,

Could you have a look at the patch on:

https://jira.sakaiproject.org/browse/SAM-1625

This prevents a hibernate object not found exception being propagated 
all the way to the portal error handler. I doubt it fixes the case 
completetly (i suspect this quizz is still very broken in our instance 
but it makes the service better behaved). The patch includes a new unit 
test that tests for this.

While investigating this I discovered:
https://jira.sakaiproject.org/browse/SAM-1636

Any objections to me cleaning that up too?

Regards

David
