Emmanuel Bernard updated ANN-549:
---------------------------------
Summary: key column of a true map should be not null when a join table is used (was: Different behavior between annotation and mapping for map key)
Assign To: Emmanuel Bernard
Of I fixed it to mimic the hbm file behavior: if an association table is involved, the key colu;m is forced to not null

> Project: Hibernate Annotations
> Type: Bug
> Components: binder
> Versions: 3.2.1
> Environment: H3.2
> Reporter: Anthony Patricio
> Assignee: Emmanuel Bernard
> Fix For: 3.2.2

> these metadatas should be considered as equivalent:
> @org.hibernate.annotations.MapKeyManyToMany
> @ManyToMany(cascade = CascadeType.ALL)
> private Map<Security, Position> positions = new HashMap<Security, Position>();
> <map name="positions" table="account_position" cascade="save-update">
> <key column="account_id" />
> <map-key-many-to-many class="Security" column="security_id"/>
> <many-to-many class="Position" column="position_id"/>
> </map>
> But we can from the generated schema that they are not:
> - annotation consider the map key as nullable column
> create table Account_Position (Account_id varchar(255) not null, positions_id bigint not null, mapkey_id varchar(255), primary key (Account_id, mapkey_id))
> - whereas mapping files consider the map key as a not-nullable column
> create table account_position (account_id varchar(255) not null, position_id bigint not null, security_id varchar(255) not null, primary key (account_id, security_id))
> Maybe there are more side effects.
> Attached are 2 testcases.
