The ListCustomer page in ERDivaLookExample is a "detail" list page.
It's very simple to configure a detail list page.
All you do is add two rules: one for the subTask key and the other for the displayPropertyKeys of the embedded D2WInspect. E.g:
entity.name = 'Customer' and task = 'list'
pageConfiguration = 'InspectEmbeddedCustomer'
