I upgraded our Dspace from 1.4.2 to 1.5 by following the steps on the manual.
Everything seems to work fine after that except when we do a search and then
click on the name of the title. I then get the message Internal System Error.
Below is the java stack displayed when I viewed the source of the page.
If anybody can help, it would be greatly appreciated.
