When you create the browse page, the page should look like this in the visual editor:
The visual editor shows the read-only form and buttons, and read-only table that make up your page, and the Structure window shows the hierarchy of the components in the page. You can reorganize the page structure by dragging components in the Structure window, or moving them in either the visual editor or source editor.
The Data Controls panel shows the structure of your business components data model. Note that the
OrderItemsView2 collection is shown as a child node of the
OrdersView1 collection, indicating the master-detail relationship between orders and order items. When you dropped this child node on your page as a table you created a table of order items for the currently-displayed order; ADF maintains this master-detail relationship for you automatically.
