Displayvalue of old Integervalues

Hi,

I have a problem with the displayvalue of old integer values (e.g. 1 = Internal, 2 = Confidential).

The notation $xx_GroupAttributes[o].[Display]$  does not work here. (Original value: $xx_GroupAttributes[o]:Int$)

I know that there was a similar post in this month with the same problem at foreign key values - but this seems not to work here.

Best regards,

Joachim
