Hi Marianne,
I can confirm it works for a sample dataset in 10.2.2
In the attached screenshots I have parcel polygons related to an owners table in a 1-1 relationship.
Overview: shows the selected parcel, the relationship class and the attributes window. The parcel has three owner records.
Rules: show the relationship rules. Here I have both subtypes in the parcel polygon related to the owners table. The residential subtype is selected.
Validate: shows the error message when the selected feature is validate.
A common mistake is not having anything checked in the destination table for the subtype or layer you want to create the relationship rule for.
Let me know if this helps.
Sean
