Hi, The trace suggests a IOException while writing to the OutputStream of the Servlet request. It is thrown by Freemaker while serializing a POJO using a Template. This indicates the rendering of a HTTP page of the Stanbol UI).
I revision 1494021 I improve the Error message for this Exception to include the Template, the rendered Object as well as the Class for the rendered Object. So when it happens again one will be able to see the type of response that was causing this. best Rupert On Mon, Jun 17, 2013 at 4:36 PM, Joseph M'Bimbi-Bene <jbi...@object-ive.com> wrote: > I got it from the restful service but once in a while and i just get > "invalid query" as a result in the web console.
