A method, apparatus and computer program product are provided for implementing persistence and refreshing of validation error messages based upon hierarchical refresh levels. A validation level is identified when a validation completes. Error messages stored in a message repository with a refresh tag level less than or equal to the validation level are removed. Then new error messages with a refresh tag level less than or equal to the validation level are collected and added to the message repository. The validation level indicates a type of validation stage that potentially updates the status of a particular error condition and message. Multiple validation levels may be represented by predefined numeric values, with larger values representing higher levels in a hierarchy.
