So if you have multiple unsaved objects that you are instructing DataMapper to save at once (say an object, plus some child objects that are attached through a relationship) and the child objects validations fail, and will not save, the whole save will fail, even if the object you're calling save on is valid. So i'd double check that your relationships are valid as well.
The other possibility is that there are constraints that are setup on the DB that are blocking the save from going through, even though datamapper thinks things are valid. One thing you could do is check out what sql is generated, or see if there's an error being thrown back. Using a logger to inspect all of this can be pretty helpful.
