There is a field called _TYPE_ (H)eader, D)etail)

In the Header line I have two String fields, one for the number of details lines ("NU_REGISTROS") and another for the sum of the detail line ("MT_TOTAL")

In the detail lines I only have a String field called "MONTO" 

I would like to build two rules. One to check the count of detail lines versus the field in the header line so I wrote :

rule "Contador de lineas detalle vs Header"

  salience 10

  when

       $numRecs : Number()

                from accumulate(Map(this["_TYPE_"] == "D", $d : this["_NUMLINE_"]), count($d))

       $map : Map(this["_TYPE_"] == "H",

                  this["NU_REGISTROS"] != $numRecs)

  then

    System.out.println("NumRecs=" + $numRecs);

    listBitacora.add(new BitacoraDTO($map.get("_NUMLINE_"),

                                          "Error en el Detalle: El número del lineas de detalle (" +  $total +

                                          ") no empareja con lo del encabezado (" + $map.get("NU_REGISTROS") + ")"));

 end

 

 However I always got "NumRecs=1" when i print out the value of $numRecs but I am absolute sure there is two details lines...

 

 Second when i try to sumarize the total field in the details line i got (MONTO in the detail line is a string):

 

 rule "Sumatoria de lineas detalle vs Header"

  salience 10

  when

       $total : Number()

                from accumulate(Map(this["_TYPE_"] == "D",

                                $monto : this["MONTO"]),

                                sum(eval(Double.valueOf((String) $monto ))))

       $map : Map(this["_TYPE_"] == "H",

                  this["MT_TOTAL"] != $total)

  then

    System.out.println("TOTAL=" + $total);

    listBitacora.add(new BitacoraDTO($map.get("_NUMLINE_"),

                                          "Error en el Detalle: El número del lineas de detalle (" +  $total +

                                          ") no empareja con lo del encabezado (" + $map.get("NU_REGISTROS") + ")"));

 end

 

 but I got

 Rule Compilation error : [Rule name='Sumatoria de lineas detalle vs Header']

        rule/Rule_Sumatoria_de_lineas_detalle_vs_Header_0.java (9:1313) : The method eval(Double) is undefined for the type Rule_Sumatoria_de_lineas_detalle_vs_Header_0

 

 Any help in those tow problems

 

 TIA
