desVar interdependencies in maestro

$

hi,

In maestro view (ADE Explorer) I have defined desVar "Vin1" which is a function of another desVar "Pin1".

Pin1 = -40

Vin1 = sqrt(2*50*10**((Pin1-30)/10))

In HB analysis when I sweep Pin1 from -40 to 0, I see Pin1 sweeping but Vin1 evaluates 3.16e-3 which corresponds to Pin1=-40. In other words, Vin1 does not change its value with the sweep. This problem is seen in maestro. ADEL didn't had this issue. In picture attached I have added netlist and maestro view. 

Is there a way we can enable desVar interdependency so that if one of them is swept, the other updates automatically?
