Hi Brian,
I'm not sure to understand your UI and the way the things are.
It might be overkill, but if you want to express those dependency, you
can create your own domain based on what it is filled so far so at
start only TypeList will be available, then "TypeList + DataTypeList"
and then "TypeList + DataTypeList + DataList"
Other than that, I don't know if it is possible to change the order...
