I have an aggregated model and I’m trying to view the Parent record in a table but all I can get it to display is the 18 character Id.

When choosing the Parent__r.Name for my grouping I get the following error:

Field must be grouped or aggregated: Name
An unexpected error has occurred. Your solution provider has been notified. (skuid)

If I choose to go through the Parent__r the Name field doesn’t show up as one of the options to choose from, rather the ID field is my only choice. This displays the 18 character ID.

Is this a bug?
