I need to create a custom field that supports multiple values which can be uniquely identified (beyond the delta field which changes when the values are re-ordered). I have created a module for the field and specified the two database columns that I would like CCK to use (one for the value and one for the ID) but I am not sure where the entry point is for adding in a unique id for each value (probably will just take the id from a sequence).
