Hi Martin,

I'm trying to initialize a collection of objects and it creates a join
query. Because I'm joining two table with many millions of records these
queries take over a minute to perform.

I noticed in the hibernate documentation that you could set the fetch type
to 'subselect' and supposedly it would not use the join for this query. I'm
not sure if that would even work, but when I tried it I found that subselect
isn't listed in FetchType. Do you know if it should be, or am I barking up
the wrong tree?

If this is an area where I can be of any service, either by adding the type
and wiring it up to hibernate or providing some exaple documentation just
let me know.
(By the way, I haven't forgotten about putting together a Teneo+SOAP
tutorial. I'm just trying to make sure all of my stuff works happily before
telling other people who to do it. However, you'll be pleased to know that
I take objects out of soap, load and save them and then return them as SOAP
quite nicely now so a tutorial shouldn't be too far off.)

Thanks for any help you can offer,

Jason
