i want to get names of all child configurations under a given parent configuration recursively.
i tried :
1-configuration.getChildren()
2-configuration.getDescendents()
but i am not able to find the result:

i have used it like this-
config = system.getConfiguration("root/testing1");
logger.info(config.getChildren().toString());

but everytime it throws error like :

Caused by: com.pmease.quickbuild.QuickbuildException: org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: com.pmease.quickbuild.model.Configuration.children, no session or session was closed
