One thing I am a bit confused is how to define validation_class for the composite column, or is there a way to define it? for the composite column, I might insert different value based on the column name, for example I will insert date for column "created": set user[1]['7:1:100:created'] = 1351728000; and insert String for description set user[1]['7:1:100:desc'] = my description; I don't see a way to define validation_class for composite column. Am I right? Thanks. -Wei
