[rules-users] Problems count and sumarizing data in facts

Hi, I have two kind of facts in a map.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 Yamil _________________________________________________________________ Escucha a quienes ya han probado Windows 7 ¡Hazlo aquí! http://www.sietesunpueblodeexpertos.com/index_windows7.html
