[Solved][ATL] string concat operation OclUndefined ??? [message #830358]

Hello

I'm trying to follow the family-person example but I ran into a problem:
the execution repeatedly tells me that neither '+' nor concat is defined for the string type. I think I did everything as it was proposed. Without concat the code runs and produces the desired output.
Trace below. I also include the source, but it is almost identical to the tutorial code...
thanks
david
