Populating a dropdown that is located in a table using a service

Hello,

I'm building an application to allow users to sign up for a vocational program. One of the forms includes a data grid listing all the different vocational areas. For other dropdowns in the application, I’ve successfully used a Service from the Service Catalog to pull vocational areas marked as "Currently available for offer?" and assigned the saved and displayed values accordingly.

However, when attempting to use the same service structure for a dropdown located in a table child form, I receive the following error: "Invalid assignment. Source and target must have the same number of lists (or tables) as ancestors."

Has anyone encountered this issue or have suggestions/workarounds for using a service-based dropdown within a table child form?
