I found an hole in typeahead updater... typeahead updater seems to be bit it by a trigger event only when there is something that have been selected... But if for instance someone select something the hidden field that get submitted is updated with the id if the record, but the hidden field is not updated if the field is empty (for some reason : USERS) after been filled once... So the id of the previous selected record stay there and the form submit correctly if there is no other validators that trigger up!!
I googled a lot about this hole and typeahead, maybe I don't have the right keywords or the issue have not been identified since bootstrap typeahead as only recently get the updated to support key/value field.
