[midPoint] Error with inbound mapping in latest build.

[Katarina Valalikova]

Hi Deepak,

I tried to replicate your problem but without success. I tested it with 
revision v3.0.1devel-19-gb708da1 . As Ivan stated, maybe the logs will 
be usefull to find out the reason.

I used both of your mappings for tests. I added column "orgdesc" into 
the .csv file and fill it with different values (a/b/c, a/b, a, empty 
value, copy&paste of your value). Then I run import accounts. Accounts 
were imported, users created and no exception was thrown.

Regards,
Katarina Valalikova
