Error on re-using the URL of export RDF in turtle format #79

Open Busa78 opened 11 years ago

Busa78 commented 11 years ago

I experience this problem when I try to access the export RDF link.

What steps will reproduce the problem?

  1. Export a project using "Export RDF as Turtle" (es. http://127.0.0.1:3333/command/core/export-rows/Bankadati-BDC-Portafoglio-Servizi.ttl) -->OK
  2. Copy the url and try to re download the same ttl file (i.e. open in another tab the same URL) give me the error.

The Error HTTP ERROR 500
