the complete type name of both Row ROOT and Product Column ROOT, it is
excluded from the relative type name Product Column.
Note If more than one type in a type tree has the same relative type name as another
in a group, then the full path of the type is exported instead of the relative type
name. No two types that have different full type names but identical relative type
names can be added to a component list.
Dragging-and-Dropping Types With the Same Relative Type Name
In the following illustration, Group Category ROOT shows that it has one type
named Item. There are two types with the same name Item in the type tree at
different places. The relative type names of both types, Item ROOT and Item
Category ROOT both evaluate to Item with respect to the Group component.
You are allowed to drag and drop only one Item into the component list. If you
attempt to drag-and-drop the second, you will be blocked and the component will
not be added to the list.
For more information, refer to the Ambiguous Type Names section.
Ambiguous Type Names
A component name can refer to more than one type. If this is true, you must
change type names so that the component name is no longer ambiguous. The
Type Designer will not allow components with the same relative type names to be
added to component lists.
