Creating pocess intance of a different process and passing arguments

Question

Creating Process instance of a different process:
I have two different process: Main_Flow (id: MainFlow) and Second_Flow (id: SecondFlow). In the first process I am reading a csv file. Each line of the file has four columns. After reading each line I have to initiate Second_Flow and pass the read data from the file. (Pls find the code below for the whole process):
     fileReader = FileReader(arg1 : fullFileName);//filename is of file type and have file name and path
     Java.Io.BufferedReader reader = BufferedReader(arg1 : fileReader);
     String str;
     int countLines = 0;
     while ((str = reader.readLine()) != null)
          strColumn = str.split(delim : ",");
               int ColumnCnt = 0;
               while (ColumnCnt < 4)
                    //defining variables
                    String appNo;
                    String custNo;
                    String loanAmm;
                    String loanDate;
                    //logMessage("Value at Column: " + ColumnCnt + " is " + strColumn[ColumnCnt]);
                    if (ColumnCnt == 0)
                         arrLoanData["appNo"] = strColumn[ColumnCnt];
                    else if (ColumnCnt == 1)
                         arrLoanData["custNo"] = strColumn[ColumnCnt];
                    else if (ColumnCnt == 2)
                         arrLoanData["loanAmm"] = strColumn[ColumnCnt];
                    else if (ColumnCnt == 3)
                         arrLoanData["loanDate"] = strColumn[ColumnCnt];
                    arrLoanData["descriptionArg"] = "AutoInstance: " + formatTime('now', timeStyle : Time.SHORT);
                    arrLoanData["genByArg"] = "Automatic";
                    ProcessInstance.create(processId : "/SecondFlow", arguments : arrLoanData, argumentsSetName : "BeginIn");
                    ColumnCnt = ColumnCnt + 1;
          countLines = countLines + 1;     
(“The code is in Java and not in PBL”)
I have to pass appNo, custNo, loanAmm and loanDate as the arguments. The Argument will be of Any[String] type. The argument set name of Second_Flow is “BeginIn”. But I am not getting anything in Second_Flow.
What can I do in the argument mapping of begin of Second_Flow to get the passed argument (array)?

Answer 1

the argument 'arguments' for the method ProcessInstance.create receives a map of the arguments that the 'argumentSetName' argument set will receive.
so for example if your second flow has 2 arguments, String name, Decimal value and String[] content your method invocation would be:
ProcessInstance.create(processId : "/SecondFlow", arguments : {"name": strNameFromCsv, "value": valueFromCsv, "content": ["a","b","c","d"]}, argumentsSetName : "BeginIn");
