Converting Application using sumo

[Jörn Dreyer via Tech-talk <tech-talk at aps.anl.gov>]

Hi,

while converting my IOC application to use sumo, I get the following error message:

error: groupdata "AREADETECTOR_3-14" must have exactly one subdir

I searched for some documentation for sumo regarding possible errors and how to solve them but did not succeed.
The relevant part of my DEPS.DB is:

                }

    }

Could that be the problem? And if, how could I solve it?
