Error exceptions.Optimisticlockexception when trying to perform UPDATE with JPA

Question

I’m having trouble when I try to perform an update with JPA with the instruction:

ObjetoDE = thisObjetoBF.update(ObjetoDE);

ERROR:

Exception [EclipseLink-5010] (Eclipse Persistence Services - 2.4.2.v20130514-5956486):
    org.eclipse.persistence.exceptions.OptimisticLockException
    Exception Description: 
        The object [ObjetoDE{ChaveUidK=355}] 
        cannot be merged because it has changed or been deleted since it was last read. 
    Class> com.xxx.yyyy.domain.admin.entity.TabelaDE

I commented all fields passing to Update only the registry key and even then persists the error, would have any idea ?

Thanks in advance.

Answer 1

I found that this occurs due to the version that is outdated and I was able to solve as follows:

ObjetoDE old = this.repository.findByID(de.getCampoChave());
        de.setUpdateS(old.getUpdateS());

The link https://www.mkyong.com/jpa/jpa-optimistic-lock-exception-in-java-development/ explains the details of this process.
