Hi Juan,

How are you calling SaveEntity()? Can you post the method where you are calling this so I can match what you are doing? I will try to recreat this situation and step through it to see what happens. I will let you know what I find.

>(1) I've forced an error on the SP by adding a RAISEERROR at the beginning of it,
>(2) built a couple of test on NUnit with different BOs of my app all trying to use saveentity or insert with SPs that have the raiserror line: all of them with the same results (Basically the saveentity method executes fine, but the data obviously does not get saved because of (1),
>(3) I've built separate methods using plain ADO.NET code against the same SP (same Nunit session) and in this case the error comes up, so this tells me it is not an ADO.NET bug.
