As is described in this post: https://stackoverflow.com/questions/36700139/hibernate-valuegenerationtype-applied-at-insert-but-not-update-time the generated values by database in timing “ALWAYS” is not working as expected
The method referenceColumnInSql is defined to return true and the method getDatabaseGeneratedReferencedColumnValue returns the value “current_timestamp”
So it is expected that the update statement also include the column and sets it’s value to “current_timestamp” but the column is missing in the update statemet and it is only included in the select statement to get the value from the database, but the value is never changed.
It is necesary to include the column in the update statement.
I think that this is a bug.
