Hello,
I have some problems in my dspace, one month ago i updated the dspace 4.5
to 5.6, and i used to use XMLUI version and now I'm using JSPUI version
with the same database. So yesterday I was trying access some collections
and the dspace and them just show : Internal System Error - The system has
experienced an internal error. Please try to do what you were doing again,
and if the problem persists, please contact us so we can fix the problem.
But this just happen in some collection, not all.
In the log file i receive this message and point to : <dspace:browselist
browseInfo="<%= bi %>" emphcolumn="<%= bix.getSortOption().getMetadata()
%>" /> and
URL Was: ...
-- Method: GET
-- Parameters were:
Exception:
java.lang.NullPointerException
