Does the Mathematical _expression_ patch not work with nested ternary logic?

This:

(IntegratorResult < Min && Value < 0) ? 0 :(IntegratorResult > Max && Value > 0) ? 0 : Value

doesn't produce the desired effect when connected to/from an Integrator patch (it looks like only the second conditional is evaluated), whereas the same logic in a _javascript_ patch:

function (__number ToIntegrator)
main
(__number Value, __number Min, __number Max, __number IntegratorResult)

{
var result = new Object();
result.ToIntegrator = (IntegratorResult < Min && Value < 0) ? 0 :

(IntegratorResult > Max && Value > 0) ? 0 : Value;
return result;

}

works fine.

Is this a known limitation of the Mathematical _expression_ patch, and if so, is there some workaround to avoid the overhead of using a JS patch?

I've attached a little demo QTZ to show the two methods in action.

Cheers,
