When loading a TimePlan that has a ResourcePlans with child Resourceplans. And then saving the child Resourceplan using:
core.DataAccess.save(DataAccess.java:89) just does: entityManager.merge(resourcePlan);
there is a Exception thrown: Saying [Duplicate entry '29' for key 1]
Im wondering whats wrong with my mapping that cause this problem.
Maybe someone can point me to a page that has solved the bidirectional mapping of Parent<-->Children<-->GrandChilden problem.
(I know I'm using EAGER-loading of all objects cause all objects are displayed to the user directly after loading them in a nice big graph.)
Hibernate does an insert instead of update on resourceplan_parent...
Hibernate:
update
resourceplan
set
resource_ID=?,
timeentry=?
where
ID=?
Hibernate:
insert
into
resourceplan_parent
(parent_ID, ID)
values
(?, ?)
