# title:        Validation could read after the end-of-file when handle multifile database
# decription:
#                  Reproduced error on WI-V3.0.1.32542 (SS/SC/CS) and WI-T4.0.0.258, WI-T4.0.0.267 (SS).
#                  Could NOT reproduce on WI-V2.5.6.27017 (SuperClassic).
#
#                  07.08.2016: removed dependency on 'employee'-  there is some strange reports about missing it.
#                  Instead of using existing 'employee', its .fbk was created (on 2.5.7), added it to fpt-repo/fbk
#                  folder and is restored here.
