DMZ 1.7.1 (DataMapper OverZealous Edition)

Im trying to figure out what is the correct order of doing this when I want to save multiple things at the same time

For example.

I have Projects. Each project has many Phases. Each Phase has one State (Florida, Texas, etc)

In my form I have the data for a New Project as well as the FIRST phase of the given project so.

this definitely shouldnt work, right?

Code:

if($project->save(array($phase, $state)))
                    {
                            redirect("Success Screen");
                    }

How should I get this done?.. keep in my mind, Its ONE form so if something from validation fails it shouldnt save anything at all
