> Bi-directional, one-to-many, ordered lists don't work
> -----------------------------------------------------
>
> Key: HIB-129
> URL: http://jira.andromda.org/browse/HIB-129
> Project: Hibernate Cartridge
> Type: Bug
> Versions: 3.1-RC1
> Reporter: Joel Kozikowski
> Assignee: Carlos Cuenca
> Attachments: HibernateMetafacadeModel.xml.zip, bi-dir-ordered-list.patch
>
> If defining a bi-directional, one-to-many association that is supposed to be
> an "ORDERED" list, the proper code to allow Hibernate to manage the index is
> not generated.
> Discussed in this post (
> http://galaxy.andromda.org/forum/viewtopic.php?p=3909#3909 ), the relevant
> information:
> Per the Hibernate FAQ at http://www.hibernate.org/193.html ....
> Assume I've set the namespace property associationEndCollectionIndexName to
> the value of "listPosition".
> If using Hibernate 2, the following additional code would need to be
> generated in the child entity's Java classes IF doing a bi-directional,
> one-to-many, ordered association:
> Code:
> private int listPosition;
> public int getListPosition()
> {
> return
> this.get<nameOfParentEntity>().get<nameOfThisEntityInParent>().indexOf(this);
> }
> private void setListPosition(int index)
> {
> // not used, calculated value, see getIndex() method
> }
> Also, the "listPosition" attribute would need to be added to the child
> entity's Hibernate HBM file.
> For Hibernate 3, the following change would be needed:
> in the parent entity's HBM file, where the <list> mapping is, the "inverse"
> attribute should be set to FALSE (it is currently set to "true").
> in the child entity's HBM file, where the <many-to-one> mapping is, the
> attributes "update" and "insert" both need to be set to false.
