Hi Bart,
so I understand that you've added an AuxClass containing the base attribute homePostalAddress.
homePostalAddress is a structured attribute with the DS syntax "Postal Address", containing a variable number of separate strings.
DSImport handles nearly all base and custom attributes, where structured values are separated with a "#" character.
However, it seems I have not yet implemented handling of this less frequently used "Postal Address" syntax.
Regards
Wolfgang
