Re: Problem with Demo Ecommerce

[BJ Freeman <bj...@free-man.net>]

I think it will go away with data reload somone playing with the back 
end, since it was specific to a product.
https://demo-trunk.ofbiz.apache.org/webtools/control/LogView

rollbackOnly was caused by: Service [calculateProductPrice] threw an 
unexpected exception/errororg.ofbiz.service.GenericServiceException: 
Service [calculateProductPrice] target threw an unexpected exception 
(null) (Service [calculateProductPrice] target threw an unexpected 
exception (null)). Rolling back transaction.
