Creating the Field Item Types
Create the Field item type and assign to it the properties that are common to all
the field types. The other field types created as subtypes of Field automatically
inherit these properties.
To create the Field types
1 Add a new item type as a subtype of the Data root type.
2 Change the properties of the new type in the Properties window:
♦ Change the Name to Field.
♦ Change the Class to Item.
♦ The default Item Subclass is Text.
3 Add the Company, ID, and PurchaseDate item types as subtypes of Field.
The Company Field and ID Field item types are correctly defined as text
items.
