Hi,

I have the following class attribute declared as a Map with the associated annotations;

@CollectionOfElements
@JoinTable(name="CREDIT_CARD_TRANSACTIONS", joinColumns = @JoinColumn(name="CREDIT_CARD_ID"))
@MapKey(columns=@Column(name="TRAN_ID"))
private Map<String, Transaction> transactions;

I use a String value as the key for the map and the Map value contains a Transaction instance. This all works fine.

I would like to override one of the column names in the CREDIT_CARD_TRANSACTION table so that it is not the default attribute value as so;

@CollectionOfElements
@JoinTable(name="CREDIT_CARD_TRANSACTIONS", joinColumns = @JoinColumn(name="CREDIT_CARD_ID"))
@MapKey(columns=@Column(name="TRAN_ID"))
@AttributeOverride(name="element.description",column=@Column(name="TRAN_DESCRIPTION"))
private Map<String, Transaction> transactions;

However doing so causes an error in which an attempt is made by Hibernate to add the attributes of the String class; value, offset, count, hashCode; into the table as so;

java.sql.SQLException: Table not found in statement [insert into CREDIT_CARD_TRANSACTIONS (CREDIT_CARD_ID, value, offset, count, hashCode, description) values (?, ?, ?, ?, ?, ?)]

The Transaction class is as follows;

@Embeddable
public class Transaction
{
@Column(length=255, nullable=false)
private String description;

...

Why does adding an @AttributeOverride annotation cause this behaviour and is there a way of achieving what I'd like to do using this annotation?

Thank you for your help.

if you can write a minimal reproducible test case, post it to JIRA. But this is really weird
