(Bug 259).
Correct directory mapping in construction space:
- Generation of names for creational operations was wrong for internally
  authenticated users.
- Stage 2 Create directory: Done left us in a bad directory.

# The LearningOnline Network with CAPA # Handler to rename files, etc, in construction space # # This file responds to the various buttons and events # in the top frame of the construction space directory. # Each event is processed in two phases. The first phase # presents a page that describes the proposed action to the user # and requests confirmation. The second phase commits the action # and displays a page showing the results of the action. # # # $Id: loncfile.pm,v 1.9 2002/05/24 05:11:40 foxr Exp $ # # Copyright Michigan State University Board of Trustees # # This file is part of the LearningOnline Network with CAPA (LON-CAPA). # # LON-CAPA is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by # the Free Software Foundation; either version 2 of the License, or # (at your option) any later version. # # LON-CAPA is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
