I have a custom fieldtype (used within Neo block) and I need to know the ID/content of entry it belongs to, when editing the entry.
I need to both populate field values based on value in other field (if present) and also perform validation on save by comparing with other fields in same entry.
So I need to know the entry content (or at least entry ID so I could fetch those) within
I know I could use
$this->element but those don't seem to provide any data related to entry
