[hibernate-issues] [Hibernate-JIRA] Created: (ANN-641) @OneToMany disables @OnDelete on @ManyToOne

@OneToMany disables @OnDelete on @ManyToOne ------------------------------------------- Key: ANN-641 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-641 Project: Hibernate Annotations Issue Type: Bug Components: binder Affects Versions: 3.3.0.ga Reporter: Christian Bauer This mapping: @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "PARENT_NODE_ID", nullable = true) @org.hibernate.annotations.OnDelete(action = org.hibernate.annotations.OnDeleteAction.CASCADE) protected Node parent; Generates the following correct DDL: alter table NODE add index FK24A602FC03E1AA (PARENT_NODE_ID), add constraint FK24A602FC03E1AA foreign key (PARENT_NODE_ID) references NODE (NODE_ID) on delete cascade; However, if you add a bidirectional collection with @OneToMany: @OneToMany(mappedBy = "parent") private List<Node> children = new ArrayList<Node>(); the DDL is missing the "on delete cascade" option. Workaround is moving the @OnDelete onto the @OneToMany: @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "PARENT_NODE_ID", nullable = true) protected Node parent; @OneToMany(mappedBy = "parent") @org.hibernate.annotations.OnDelete(action = org.hibernate.annotations.OnDeleteAction.CASCADE) private List<Node> children = new ArrayList<Node>(); This is not intuitive, and if the binding can't be changed, needs to be documented. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
