We have kind of an odd environment where our domain model configuration is a mix of annotation and .hbm.xml files. What I noticed is that for entities having .hbm.xml configuration, auto indexing didnt work even with added post update listeners. I have two questions
1. Should we need listeners in such mixed environment?
2. What configuration might be missing which is causing indexing to not kick off at commit

current work around is to do it manually, but that makes it non-transactional. We are using Hibernate Search 3.1.1GA

so, I think I know reason now. Its similar to viewtopic.php?f=9&t=996636&start=0
My relationship is as follows:

Obj A --OneToOne-> Obj B -ManyToOne-> Obj C

I want to search for object A and object B, based on properties of object C. When object C updates, there is no cascade to A and B, so I ll have to index related Obj A and Obj B manually. I guess the only piece remaining is to configure custom listener that can be called during commit.
