Hi ifthekar,
I think it is a newly imported SWCV. Try this work around
open SWCV (double click on swcv)
- enter edit mode
- change something (description)
- save
- change it back
- save
- create namespace
once one namespace is created it will not occur again. do the above 2 3 times and try 2 to 3 times if dsnt work in one time.
Regards,
Vikas
