When running a unit test on the controller save method, for some reason a grails models save method returns simply null

So we have a unit test which is failing where we attempt to call the save method on a model. This for some reason returns true when we run the method in reality. We've mocked the domain in the setUp method.

Does anyone know why the heck the save method is returning null?

this might be an issue if you are using 1.3.3.
