use of org.jaffa.exceptions.LabelException in project jaffa-framework by jaffa-projects.

the class LabelHelper method performSave.

/**
 * This will perform the following tasks.
 * - Add an entry for each label having an override value, to the ApplicationResources.override file.
 * - Remove all entries from the ApplicationResources.override file, for which the override value is blank
 * - Migrate all changes to the ApplicationResources.properties file by invoking InitApp.generateApplicationResources()
 * - Flush the struts properties cache by invoking the flushCache() method on the MessageResources, provided its an instance of 'org.jaffa.util.PropertyMessageResources'
 * @param request The request we are processing.
 * @param messageResources The MessageResources object, which will be flushed, if its an instance of 'org.jaffa.util.PropertyMessageResources'.
 * @throws FrameworkException if any error occurs.
