Open a record or export data and get error saying "The cache could not be updated. Error: ExecutionException (org.hibernate.exception.GenericJDBCException: could not load an entity: [edu.ku.brc.specify.datamodel.xxx"

Cause: The record is trying to open an associated record that it cannot find either because it is not there or because the record has invalid data (for example, invalid dates "00-00-0000").

Resolution: Tim can find the records that are missing via MySQL. They either have to be reassigned to an existing record, or cleared of the association. If the error is because there is invalid data, the data has to be resolved.
