Adding worker: Worker [name=1, passwrod=12, account=Account [username=admin, email=admin@kokade.com, auths=[ROLE_RESTRICTED_USER, ROLE_ADMIN, ROLE_USER]]]

Reqested to save Worker [name=1, passwrod=12, account=Account [username=admin, email=admin@kokade.com, auths=[ROLE_RESTRICTED_USER, ROLE_ADMIN, ROLE_USER]]]

But,

Hibernate: insert into Worker (password, name, account_username) values (?, ?, ?)
WARN  - JDBCExceptionReporter      - SQL Error: 0, SQLState: 23502
ERROR - JDBCExceptionReporter      - Batch entry 0 insert into Worker (password, name, account_username) values ('12', NULL, NULL) was aborted.  Call getNextException to see the cause.
WARN  - JDBCExceptionReporter      - SQL Error: 0, SQLState: 23502
ERROR - JDBCExceptionReporter      - ERROR: null value in column "name" violates not-null constraint


Any reason why it's trying to insert values= NULL instead of the ones from the object?
