It's saying that your dropdown uses a list of valid values (held in local!laCreditActions) but that actual value assigned to the component (ri!requestedId_int) isn't in that list. Note that both the value and the data type of the value have to match (a mismatched type might explain why the error messages seems to be telling you the value being used does appear to be in your list of valid values)
