Note2: This function tries to automatically avoid an infinite recursion loop by using a $blacklist: for a given constrained custom field, a table won't be visited twice. This means that for example you can do: invoice->user->socpeople->invoice, this will work and every referenced fields will be fetched, but it will automatically stop the recursion at the second invoice, because else it could continue in a loop to user, socpeople, invoice, user, socpeople, etc. | Note2: This function tries to automatically avoid an infinite recursion loop by using a $blacklist: for a given constrained custom field, a table won't be visited twice.

Note3: when adding recursively referenced fields, the key in the returned array will be prefixed by the name of the custom field that led to those remote fields. Thus, you can have something like "cf_myfield1_cf_remotefield1_cf_remotefield2" if you have a constrained field cf_myfield1->cf_remotefield1->cf_remotefield2. | |||
