The field status (invalid/valid) is related to the results of the extraction (ExtractionConfident), the defined formatting and the applied validation rule that is attached to the field. During server processing state of the field is following the scheme in the flowchart below. After extraction, the field formatter and then the validation rules are processed for each field as defined. The arrows in the figure show how the field state may change during validation checks. For example, a field formatter can either keep the current state of the field or change a "Valid" field state to "Invalid", but it cannot change an "Invalid" field state to "Valid". A validation rule can only change a field's state from "Invalid" to "Valid", when "Make uncertain results valid" is selected in the properties of the validation rule.
