A lookup is an actual class made up of:
| Attribute |
Type |
Description |
| id |
String |
The GUID of the item. Required for set. |
| type |
Integer |
Deprecated. The entity type code. |
| typename |
String |
The entity name of the item. Required for set. |
| name |
String |
The name of the item to be displayed. Required for set. |
There won't be any such lookupItem.new_value. That being said, you can put whatever string you want at name and I will even appear. However, the next time the record renders it will show up with the "correct" name of that record because the application
is building the lookup from the data in the data base.
Lookup fields are arrays of length 1 and the typename has to match the type of the entity assigned to that field.
Customer fields are lookup arrays of length 1 where the type can be either an Account or a Contact.
etc
Am I even close to answering your question?
