Manual indexing in Seam

I'm trying to do something I thought was simple: manually indexing an entity in Seam. But I keep getting the following error:

object is not an instance of declaring class

I've searched around and found out something about an "unproxy" method but I'm not sure that applies. The code looks like this:

Code:

FullTextEntityManager ftem = (FullTextEntityManager)entityManager;
MyClassToIndex myClass = ftem.find(MyClassToIndex.class, id);
ftem.index(myClass);

The exception occurs in sometime during the index method. Here is the relevant part of the stack trace:

Code:

Any ideas? Seems like there is a simple fix to this. I'm using Seam 2.2.1, Hibernate 3.5.4 and Hibernate Search 3.2.2-SNAPSHOT.

Why Hibernate Search 3.2.2-SNAPSHOT ?
Could you please try 3.3.0.Final

I'm was using 3.2.2-SNAPSHOT due to this issue:

viewtopic.php?f=9&t=1006616&start=0

But I switched to 3.3.0.Final (and consequently Hibernate 3.6.0.Final) and the index function seems to work.

Thanks!

any fix in old branches will also be fixed in never releases, while the opposite isn't true; so unless you got the enterprise version (which has support and backport of fixes for a loong time) you'd likely want to keep up to date with latest releases.
