Problem in Adding New Connection Broker

Fakhar

Hi

     I am using Documentum Developer Edition 7.1 in CentOS (Linux) environment. I am trying to create a new connection broker. When i click "Add Repository" in end of left explorer, it navigates me to a page, where i have to select one of old repositories (MyRepo in my case). But list that is to show repositories names is empty. Don't know why. Please guide.
