The problem is when we have to add multiple actions to a form, and each
of them modify the object in different ways (say). In such a case, we
cannot use the form.EditForm as is. We need to add more actions
explicitly. And, if we have to notify(IObjectModifiedEvent) everytime,
for the object to be persisted, it does not seem nice.

I would have been happy if the transaction failed completely. But, it
had not. The transaction was successful. Subsequent requests on the same
object show that the previous modifications are intact. The object's
changes just did not make it to the disk.
