[hibernate-issues] [Hibernate-JIRA] Created: (HHH-6593) Fetch joining subelements of a one-to-one or many-to-one association

Fetch joining subelements of a one-to-one or many-to-one association -------------------------------------------------------------------- Key: HHH-6593 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6593 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.6.6 Reporter: Christian Beikov Priority: Critical The problem is discussed on the forum a long time ago. I just found the topic and i wanted to report that this bug is still available in 3.6.6 https://forum.hibernate.org/viewtopic.php?f=1&t=987905&start=0 Here a concrete example from my usecase: class A{ private B b; } class B{ private Map<String, C> map; } class C{ private String c; } Just imagine that the classes and fields would be annotated right ;) Now the problem in my case was that i wanted a list of A elements with fetch joined B and of course it's map. I tried the following query: FROM A a LEFT OUTER JOIN FETCH a.b bElem LEFT OUTER JOIN bElem.map cMap and i got a NullPointerException just like the users which posted in the given topic. My workaround was: FROM A a LEFT OUTER JOIN FETCH a.b bElem LEFT OUTER JOIN a.b.map cMap The main problem now is, that i have a dynamic fetch profile system which won't work correctly if this issue is not solved. -- This message is automatically generated by JIRA.
