java - Hibernate Collection is Null on update -


consider following:

@entity public class mainentity {       @onetoone(orphanremoval = true, cascade = cascadetype.all)     private childentity childentity; }  @entity public class childentity {       @onetomany(cascade = cascadetype.all)     @lazycollection(false)     private list<anotherentity> otherentities; } 

now, when first call

final childentity anewchild = new childentity();     anewchild.addotherentity(anotherentity); //several entities can added here     mainentity.setchildentity(anewchild); entitymanager.persist(mainentity); 

everything works fine, , updates, long after transaction finished.

final childentity anothernewchild = new childentity(); anothernewchild.addotherentity(anotherentity); //several entities can added here mainentity.setchildentity(anothernewchild);  //a log of log.info(mainentity); shows fields appropriately set //at point during merge operation, new childentity need persisted.  //according logs, invocation of entitymanager.persist(anothernewchild) occurs, during merge propagated new entity. //at point childentity.otherentities detected null return entitymanager.merge(mainentity);  

the problem that, persist,

list<anotherentity>

is not null , not empty, while on merge,

list<anotherentity>

is null

i doing on ejb remote invocation.

https://github.com/marembo2008/hibernate-jpa-bug

opened issue on hibernate issue tracker.
