Thanks for the prompt response on this issue. Pinaki, I took your suggestion and explicitly added this FetchGroup to the entity manager FetchPlan. Initially this seemed to be working, but I am now running into a somewhat more complex issue. The issue manifests itself when there is a 'container' class which has a OneToOne reference to an 'entity' class, and the 'entity' class has a OneToMany self-reference as in my previous example. Here, when I first create an object graph where an instance of the 'container' class references the same entity graph in the previous example, I can save the graph and then load the graph and the specified recursionDepth is being honored. If I then delete the 'container' object (which cascades the delete to the 'entity' graph), the delete occurs correctly. But, if I then create/save a new graph of objects, the subsequent load of this new graph does not honor the recursionDepth.
It should be noted that I needed to specify FetchGroups on both the OneToOne and OneToMany references described above in order to get the initial load of the graph to succeed. I have attached a new test case which reproduces this issue. Again, thanks in advance for any assistance that can be provided. - Brian http://n2.nabble.com/file/n2272348/openjpa_recursion_test_v2.jar openjpa_recursion_test_v2.jar Donald Woods wrote: > > If you moved the @LoadFetchGroup from the getSubEntities() method to > where the m_subEntities property is defined, would that also work? > > > Fetch group docs - > http://openjpa.apache.org/builds/latest/docs/manual/manual.html#ref_guide_fetch_custom > > > -Donald > > > Pinaki Poddar wrote: >> Hi Brain, >> You have defined a FetchGroup named "subEntities" with arecursion >> depth >> of 50 alright.
