Note2: Validation Unit property
Description
Specifies the scope of form validation at runtime. Specifically, the validation unit defines the
maximum amount of data that an operator can enter in the form before Form Builder initiates
validation. For most applications, the Validation Unit is Item (default setting on most platforms),
which means that Form Builder validates data in an item as soon as the operator attempts to
navigate out of the item.
