Re: Problem with Windsor null reference exception
Berke Sokhan
Got all sources from git/castleproject source and git/haf/castle.facilities.nhibernate built them. But NH facility uses Windsor 2.5.1, and I dont want to downgrade to it. I already spent too much time try to integrate the new nh facility. I also noticed old NHIntegration facility uses an old version of Castle.
So may I ask you guys, to achive session-per-call/tx-per-call nhibernate WCF application server (that is not using IIS or httpbinding), excluding nhfacilities and including wcf facility...
Can you guide me to a best practice?

Hmm, I don’t know how to fix this properly...
The only work-around so far for me is to downgrade Windsor to 2.5.1. That works. I suggested that some of the improvements from v3 might be back-ported to change some of the bits in Windsor and make it go away.

I am using Henrik's version of Transactions/AutoTx lib coming with new NH Facility.
And I get this exception when registering some POCO service class which have "Transactional" attribute on it (removing attr. prevents exception, but nh facility need it to open injected session).
My early impression was AutoTx has some bug in inspecting attributes, maybe a null check before adding to interceptors collection obviously ...
Will look at source and try to point exact location.

If you can reproduce it in a way that points to some reasonable bug in Windsor or elsewhere...
I looked at it when Henrik originally reported it but other than "that's bizarre it can't be happening" I didn't find any good explanation for that.

I was wondering if I could get some help debugging this exception?

Windsor 2.5.2, 2.5.3 are affected. Not 2.5.1.xxxx
