Filter Combo Box based on a entity relationship and show a child field value
I have three entities Lease, LeaseDetail, and Building. When a lease is selected in a gallery, I would like the user to select the related lease detail, but I would like for the combo box to show the building related to the lease.
Filtering the details related to the lease is working fine, but it appears that the related building is not showing on the detail record?
I am able to show other fields, but how can I show the related building? It is a One to Many relationship so there is only one building related to the detail...
