Hi soja,

Can you explain how you define the list in the Java service task?

I'm having the same problem here.

hi nitroin,

define a java service task , and assign a java class to this task, with the below code:



package makeMYusers;

import java.util.ArrayList;
import java.util.Collection;
import org.activiti.engine.delegate.DelegateExecution;
import org.activiti.engine.delegate.JavaDelegate;

public class mylist  implements JavaDelegate {

 @Override
   public void execute(DelegateExecution execution) throws Exception {
     Collection<String> USlistName = new ArrayList<String>();
     USlistName.add("name1");
     USlistName.add("name2");
     execution.setVariable("nameList", USlistName);
    
  }
  
 }

"nameList" is the variable , that you should define it , and use it in the multi instance section of the task rpopertise, which you want to run in multi instance mode.
