[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-4262) Cascade operations don't take affect through a @CollectionOfElements

Cascade operations don't take affect through a @CollectionOfElements -------------------------------------------------------------------- Key: HHH-4262 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4262 Project: Hibernate Core Issue Type: Bug Components: annotations Environment: Hibernate 3.2.5 Reporter: Chris L Assignee: Gail Badner Consider having three classes. The first is an @Entity called a View, which has a collection of @Embeddable Column objects. Column objects have an @ManyToOne relationship to a @Entity called Filter. The three classes have a very straightforward mapping: @javax.persistence.Entity() @Entity(dynamicUpdate=true) @Table(name="PORTFOLIO_VIEW") class View { .... @JoinTable(name="PORTFOLIO_VIEW_COLUMN",joinColumns={@JoinColumn(name="VIEW_ID")}) @IndexColumn(name="COLUMN_INDEX") @Cascade(CascadeType.ALL) @LazyCollection(LazyCollectionOption.FALSE) @CollectionOfElements private List<Column> columns; .... } @Embeddable class Column { .... @ManyToOne(fetch=FetchType.EAGER) @Cascade(CascadeType.ALL) @JoinColumn(name="FILTER") @Target(FilterImpl.class) private Filter filter; .... } @javax.persistence.Entity @Entity(dynamicUpdate=true) @Table(name="FILTER") @DiscriminatorColumn(name="CLASS_NAME",length=255) abstract class FilterImpl { .... } When I create a new view, with a new column and filter object, I should be able to save the view and have the @Cascade settings on the @CollectionOfElements and the @ManyToOne inside of Column take affect, and save the Filter. Instead, I get a TransientObjectException because the Filter hasn't been saved yet. I know I could work around this by either making Column an Entity, or by adding code to save the Filter before saving the View. But it seems to me this is reasonable usage of an Embeddable.
