In that case you must include all the attributes you want to display on the page to
become a part of the view object on which you base your group in the Application
Definition. So the CountryName attribute of the Countries View must be added to the
LocationsView.
Perform the following steps to accomplish this:
1. Select the view object you want to modify, right mouse click, and select Edit
2. Navigate to the Entity Objects node. You will notice that your base entity is at
the right hand side as the selected entity. To be able to include lookup attributes
you must select the lookup entity and move it from the Available list to the
Selected list.
3. Set a proper alias for the lookup entity and select the right association end
(dropdown list just below the Selected Entities box).
4. Navigate to the Attributes node. You will notice that all the attributes of the base
entity take part of the selected list. Now, in the Available list, select those
attributes from the lookup entity object you want to display in the view object,
and move them to the Selected list.
