Rob,
I was able to get it fixed.  You should be able to patch and rebuild just a small part of osp.  Do you know how to get the diff out of that jira?  It's small enough that you could make the change by hand and then just rebuild osp (or just osp/presentation).

Chris,

Are we near a solution yet?  Will this likely be a patch or a complete rebuild?

Thanks.

Rob,
Looks like a change made in this jira (http://jira.sakaiproject.org/browse/sak-18742) is now causing this problem.
No solution yet, but didn't want to leave you hanging!

Rob,
I was able to reproduce the error on a 2.7.x nightly instance so it's not likely anything that you've done wrong.  I'll take a look and get back to you!

Hi,
.
I built Sakai 2.7.1 from source using Maven 2.2.1 and then installed same in Tomcat 5.5.31.  The System runs on Redhat ES 5.   I followed the install from source instructions on the Sakai Project website (URL: <http://confluence.sakaiproject.org/display/DOC/Sakai+2.7> http://confluence.sakaiproject.org/display/DOC/Sakai+2.7), including setting java_opts within Tomcat, etc.  I also tailored a sakai.properties file so as to include a proper URL and title.  I assume that “By default, all Sakai distributions are configured to use an in-memory version of HSQLDB” means that I can leave database configuration alone at least until I’ve tested everything.

Here’s the problem.  I created a new user, me, and I also created a new worksite and within that worksite I added a portfolio.  For the portfolio, I chose Simple HTML and added a page containing only the line “My Portfolio”.    When I clicked on the link to view the portfolio, the response was “An unexpected error has occurred.”  And along with that, a lengthy StackTrace (included below).

This is my first time playing with Sakai, so I’m not sure what other useful information I can provide.  Any idea why I’m getting the exception?

Thanks,
