Saving thread killed by exception

xdm

I get this exception with Ice-3.1.1

04/25/07 18:54:33.274 CommerceService-Commerce: error: Saving thread killed by exception: EvictorI.cpp:1574: Freeze::DatabaseException:
N2Oz8Commerce12CorporationIE does not implement IceUtil::AbstractMutex

CorporationI extends OnRezI and OnRezI extends IceUtil::AbstractMutexReadI<IceUtil::RWRecMutex>

I have lot of class that Extends OnRezI in other services and use Evictor for persistence and never see this exception. Any Ideas.

I now updating to Ice-3.2.0 to see if this solve the problem.

xdm

Problem seems to be that i don't use public inheritance in CorporationI

this don't work

class CorporationI : virtual public Corporation,virtual Oz::Base::OnRezI{

this works

class CorporationI : virtual public Corporation,virtual public Oz::Base::OnRezI{

thanks in any way
