efsInternal not returning boolean

[Dave180]

Test(): a = -785 b = -808 c = 1 d = false e = 1 Vol = 14
Test(): a = -785 b = -809 c = 1 d = false e = 1 Vol = 14
Caller(): a = -785 b = -809 c = 1 d = null e = 1
Test(): a = -785 b = -810 c = 1 d = false e = 1 Vol = 14
Caller(): a = -785 b = -810 c = 1 d = null e = 1
Test(): a = -785 b = -811 c = 1 d = false e = 1 Vol = 15
Test(): a = -785 b = -812 c = 1 d = false e = 1 Vol = 15
Caller(): a = -785 b = -812 c = 1 d = null e = 1

A slightly modified version of the code in my previous post about missing NEWBARs produced the above output.
The change to the test prog was to return a "false" value as another member of the array.
See that the caller receives a null instead of a false.
A bug?

    var d = false;
    var e = 1;
    debugPrint("Test():   "   + "a = " + a + " b = " + b  + " c = " + c  + " d = " + d  + " e = " + e + " Vol = " + volume() + "\n");
    return new Array(a,b,c,d,e); 

    debugPrint("Caller(): a = " + getSeries(ms,0).getValue(0) + " b = " + getSeries(ms,1).getValue(0) 
                      + " c = " + getSeries(ms,2).getValue(0) + " d = " + getSeries(ms,3).getValue(0) 
                      + " e = " + getSeries(ms,4).getValue(0) + "\n");

efsInternal() and efsExternal() only return values that are numbers

Thanks.
Perhaps eSignal could make the documentation clearer. I see nothing that makes it obvious that restriction exists.
