How to pass diffrent data value to Alfresco activiti multi instance sub process

rahiakela

I have created a multi instance sub process and the number of sub process is created dynamically using Multi-Instance's loopCardinality element but my problem is that I am not able to pass diffrent-diffrent data value to each sub process.

This is my problem scenario  as shown in the below image.I want to divide sub process based on loopCardinality value like:-

int getSubProcessDataValue(int fileCount,int  loopCardinality){

   if(fileCount < 1 && loopCardinality < 1)

       return 0

    int result=fileCount/loopCardinality;

    return result;

}

Suppose fileCount=7 and loopCardinality=2 then the above function will return 3 for first sub process.It means I have to pass 3 file names to first sub process.

int getLastSubProcessDataValue(int fileCount,int  loopCardinality){

   if(fileCount < 1 && loopCardinality < 1)

       return 0

    int result=fileCount/loopCardinality;

    int rem=fileCount%loopCardinality;

    return result+rem;

}

Suppose fileCount=7 and loopCardinality=2 then the above function will return 4 for last sub process.It means I have to pass 4 file names to last sub process.

Anyone have an idea how to implemet it ? please help me.

I have done it using TaskListener as shown below code:

package com.knovel.workflow.scripts;&nbsp; import java.util.ArrayList; import java.util.Arrays; import java.util.List;&nbsp; import org.activiti.engine.delegate.DelegateTask; import org.activiti.engine.delegate.TaskListener;&nbsp; public class FileSplittingTaskListener implements TaskListener{&nbsp; private static final long serialVersionUID = 3972525330472103945L;&nbsp; @Override public void notify(DelegateTask task) {&nbsp;&nbsp;&nbsp;&nbsp; System.out.println("#####FileSplittingTaskListener######");&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; task.setVariable("bpm_assignee", task.getVariable("bpm_assignee"));&nbsp;&nbsp;&nbsp;&nbsp; task.setVariable("bpm_comment", task.getVariable("bpm_comment"));&nbsp;&nbsp;&nbsp;&nbsp; task.setVariable("bpm_dueDate", task.getDueDate());&nbsp;&nbsp;&nbsp;&nbsp; task.setVariable("bpm_priority", task.getPriority());&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; String strFileSplitter=(String)task.getVariable("wf_fileSplitter");&nbsp;&nbsp;&nbsp;&nbsp; System.out.println("#############FileSplitter >>"+strFileSplitter);&nbsp;&nbsp;&nbsp;&nbsp; Integer fileSplitter=Integer.parseInt(strFileSplitter);&nbsp;&nbsp;&nbsp;&nbsp; System.out.println("#############FileSplitter >>"+fileSplitter);&nbsp;&nbsp;&nbsp;&nbsp; //task.setVariable("wf_taskCounter", fileSplitter);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; String workFlowFileName=(String)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; task.getVariable("wf_workFlowFileName");&nbsp;&nbsp;&nbsp;&nbsp; String[] files=workFlowFileName.split("-");&nbsp;&nbsp;&nbsp;&nbsp; System.out.println("#######Files Length:"+files.length);&nbsp;&nbsp;&nbsp;&nbsp; List<String[]> filesList = splitArray(files, fileSplitter);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; List<String> fileList=new ArrayList<>();&nbsp;&nbsp;&nbsp;&nbsp; for (String[] lists : filesList) {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; String fileName="";&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int srNo=0;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int count=1;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for (String string : lists) {&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; System.out.println("File>>"+string);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if(count == lists.length){&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fileName=fileName+ ++srNo +"-"+string;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }else{&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fileName=fileName+ ++srNo +"-"+string+",";&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; count++;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fileList.add(fileName);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; srNo=0;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; System.out.println("FileList>>"+fileList);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; System.out.println("#############FileList >>"+fileList);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; task.setVariable("filesList", fileList);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; public static <T extends Object> List<T[]> splitArray(T[] array, int&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; max){&nbsp;&nbsp;&nbsp;&nbsp; int x = array.length / max;&nbsp;&nbsp;&nbsp;&nbsp; int r = (array.length % max); // remainder&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; int lower = 0;&nbsp;&nbsp;&nbsp;&nbsp; int upper = 0;&nbsp;&nbsp;&nbsp;&nbsp; List<T[]> list = new ArrayList<T[]>();&nbsp;&nbsp;&nbsp;&nbsp; int i=0;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; for(i=0; i<x; i++){&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; upper += max;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; list.add(Arrays.copyOfRange(array, lower, upper));&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; lower = upper;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if(r > 0){&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; list.add(Arrays.copyOfRange(array, lower, (lower + r)));&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; return list;&nbsp;&nbsp;&nbsp;&nbsp; }&nbsp;&nbsp; }

And I have updated multiInstanceLoopCharacteristics element properties as shown below:

<multiInstanceLoopCharacteristics&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; isSequential="false"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; activiti:collection="filesList"&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; activiti:elementVariable="wf_workFlowFileName"> </multiInstanceLoopCharacteristics>

Thank you so much for your valuable supports!!!
