NotesItem (JavaScript™)
Represents a discrete value or set of values in a document. The client interface displays items in a document through fields on a form. When a field on a form and an item in a document have the same name, the field displays the item (for example, the Subject field displays the Subject item). All items in a document are accessible programmatically, regardless of what form is used to display the document in the user interface.
setValueCustomDataBytes (NotesItem - JavaScript™)
Sets the value of an item to custom data from a byte array.
