LFunc.ResultType:='array of Boolean'; can not used when run script.

[wqmeng]

Hello,

I add a custom function and register it to DWScript.

  LFunc:=FdwsUnit.Functions.Add;
  LFunc.Name:='Add_Array';
  LFunc.Overloaded := True;
  LFunc.OnEval:=dwsUnitAdd_Array_Eval;
  LFunc.ResultType:='array of Boolean';
  LParam:=LFunc.Parameters.Add;
...

And in the dwsUnitAdd_Array_Eval function, I use the following code to return the result array.

  Res := Info.ResultVars.ScriptDynArray;
  Res.ArrayLength := Count;

  for I := 0 to Count - 1 do
    Res.SetAsBoolean(I, ResultArray[i]);

Then will get error report Message: Syntax Error: TdwsUnit: "TradeBase" -- TdwsFunction: "Add_Array" -- DataType "array of Boolean" not found

So I'm confused, is the absence of "array of Boolean" a result of design, or is it a bug?

As if I change the result type as 'array of float', that fine, but when use the function BoolToStr(res_array[0]) in script side, it will report except a Bool value but get a Float value, So have to compare to 0 BoolToStr(res_array[0] <> 0), and could get the 'True' or 'Flase' string.

Thank you very much.
