Okay, I tried it and slo far it seems to work nicely.

Here's what I added to GlorpSession:

rollbackAndContinue
    "A shorter synonym"
    ^self rollbackUnitOfWorkAndContinue.

rollbackUnitOfWorkAndContinue
    "Rollback the current unit of work, but then keep going with the same set of registered objects, with their state updated to reflect current values."

    | registeredObjects |  
    currentUnitOfWork isNil ifTrue: [^self error: 'Not in unit of work'].
    registeredObjects := currentUnitOfWork registeredObjects.
    currentUnitOfWork newObjects do: [:each | registeredObjects remove: each].
    self rollbackUnitOfWork.
    self beginUnitOfWork.
    self registerAll: registeredObjects.

So far, it seems I have no troubles and have no need to re-register or refresh objects after a rollback, since the re-registering is done in rollbackUnitOtWorkAndContinue.

Since I am neither using a current version of GLORP, nor have a current version of VW at my fingertips, I cannot publish any changes to Glorp anywhere. But they're probably in a good place on this list if anybody wants to harvest the code into a new release.

Thanks, Alan, for your hints. Please feel free to tell me if my thinking about new objects is wrong (since I am not completely sure).
