I did step by step from Extended-user howto. Does your doSelectJoinXXX 
working good?
It seems to be offset in poulateObject specially for that case, when 
object data isn't in 1th. index. If I interpreted well doselectjoins, it 
  append an extra columns to object for user field and
make a portaluser object into this. The Sql field orders is 
baseobjectfields and then userfields. It is force to populating user 
object form an offset.

And when I change to
Value value = row.getValue(j + offset)
it is working good.
