Versions:
Seam 2.1.0.CR1
hibernate-search 3.0.1.GA

I have two entities which I want to manually index, viz. Product, and ProductInfo (OneToMany relationship)
I get an exception when I index ProductInfo.

I'm getting the following exception while running a manual index operation.

I'm sorry for the late answer, we from the Search team don't notice all posts on the wrong forum. Hibernate Search related questions should be posted on the Search forum.

If you still need help, please post to the correct forum.
