Examples of org.apache.isis.applib.RepositoryException

org.apache.isis.applib.RepositoryException
Indicates that a repository method has failed.
This exception is intended to represent an unexpected and non-recoverable condition (eg a syntax error in some JDOQL query syntax or similar), and so is a subclass of {@link NonRecoverableException}. Throwing this exception will therefore result in (some sort of) error page being displayed to the user. @see NonRecoverableException @see RecoverableException
