I'm saying this feature is irrelevant to the problem.
 
Whether it can resolve circular references is a seperate issue for the dependency mechanism to spot.
The order in which you change the state of things shouldn't make a difference.
 
If A depends upon B which then depends upon A all at stage 1, it does not matter whether you do:
 
change(A, stage1);
change(A, stage2);
change(B, stage1);
change(B, stage2);
checkComplete(A, B);
 
or
 
change(A, stage1);
change(B, stage1);change(A, stage2);
change(B, stage2);
checkComplete(A, B);
 
The result should be the same.
 
If you add more checkComplete()s between the steps then obviously it is going to report an incomplete
deployment until A and B are both at stage1.
 
change(A, stage1);
checkComplete(A); // Oops, IncompleteDeploymentException - A depends B which is not in the correct state yet, so A is not at stage 1 either.
