Hi All,
I am trying to add some error handling around the UnitOfWork methods. I have something similar to below
Using uow = session.StartUnitOfWork()
For each Person in myCollection
Dim newPerson As IEntity = session.Source.CreateNew("Person")
bag.PutValue(myField, newValue)
Try
bag.ChangeEntity(session, newPerson, True)
uow.Put(NewPerson)
Catch ex As Exception
'logout: ViException.ErrorString(ex)))
End Try
Next
uow.Commit()
End Using
In some instances bad data causes the uow.Put() method to throw an error and the exception is triggered, however from that point on I am no longer able to use the uow object as it receives this error:
[810300] This unit of work contained errors and can't be used for further operations.
So what I am after is a way to remove the last object added to the UnitOfWork so it can continue processing.
I see there are methods such as uow.flush() and uow.dispose()
Has anyone used these methods? I am running version 7 and my Object Layer documentation doesn't seem to work since the dell hosted urls were closed down, so I haven't been able to find any documentation on these methods as they are not used in the sample scripts. Does one of these methods allow the last object to be removed from the UnitOfWork, so I could call it from a finally block?
I could add additional validation to the data coming in to try and prevent the error occurring, however it would be nice to have the error handled and not prevent the remaining bulk updates from occurring.
