   The error specifically indicates that undefined variable or class name: workflowAssignment This could mean it wasn't initialized properly. Try the below code to verify the same. 

   if (workflowAssignment != null) {
       LogUtil.info("Value of workflowAssignment : ", workflowAssignment.toString());
   } else {
       LogUtil.info("workflowAssignment is null","");
   }

   
   

   Additionally check if you have imported the necessary package

   import org.joget.workflow.model.WorkflowAssignment;

   
   

   Let us know if this works. Please share your full beanshell script if possible for further debugging.

   and here now the two scripts:

   
   

   This is working:

   Route A has a transition to Tool B.

   Bean in Route A

   import org.joget.workflow.model.DecisionResult;
   import org.joget.commons.util.LogUtil;
   import org.joget.workflow.model.service.*;
   
   
   String groupsRequested = "#form.account_signup.groupsRequested#";
   int groupsRequestedArraySize;
   String[] groupsRequestedArray = groupsRequested.split(";");
   
   if (groupsRequested != "") {
       groupsRequestedArraySize = groupsRequestedArray.length;
   } else {
       groupsRequestedArraySize = 0;
   }
   
   int groupCounter = Integer.valueOf("#variable.groupCounter#");
   
   
   //LogUtil.info("Value of groupCounter             : ", "" + groupCounter);
   //LogUtil.info("Value of groupsRequested          : ", groupsRequested);
   //LogUtil.info("Value of groupsRequestedArray     : ", Arrays.toString(groupsRequestedArray));
   //LogUtil.info("Value of groupsRequestedArraySize : ", "" + groupsRequestedArraySize);
   
   
   DecisionResult result = new DecisionResult();
    
   if (groupCounter >= groupsRequestedArraySize ) {
       result.addTransition("noGroupUpdate");
   //    LogUtil.info("Value of Transition             : ", "noGroupUpdate");
       
   } else {
       result.addTransition("groupUpdate");
   //    LogUtil.info("Value of Transition             : ", "groupUpdate");
   }
    
   result.setIsAndSplit(true);
    
   return result;

   Bean in Tool B

   
   

   import org.joget.commons.util.LogUtil;
   import org.joget.workflow.model.service.*;
   
   
   String groupsRequested = "#form.account_signup.groupsRequested#";
   
   String[] groupsRequestedArray = groupsRequested.split(";");
   
   int groupCounter = Integer.valueOf("#variable.groupCounter#");
   
   //LogUtil.info("Value of groupCounter             : ", "" + groupCounter);
   //LogUtil.info("Value of groupsRequestedArray     : ", Arrays.toString(groupsRequestedArray));
   //LogUtil.info("Value of workflowAssignment       : ", workflowAssignment.toString());
   
   String group = groupsRequestedArray[groupCounter++];
   
   WorkflowManager wm = (WorkflowManager) pluginManager.getBean("workflowManager");
   wm.activityVariable(workflowAssignment.getActivityId(),"group", group);
   wm.activityVariable(workflowAssignment.getActivityId(),"groupCounter", String.valueOf(groupCounter));
   
   //LogUtil.info("Value of groupCounter             : ", "" + groupCounter);
   //LogUtil.info("Value of group                    : ", "" + group);

   
   

   This is not working:

   All code is in the Bean for Route A, not Tool B.

   
   

   import org.joget.workflow.model.DecisionResult;
   import org.joget.commons.util.LogUtil;
   import org.joget.workflow.model.service.*;

   
   String groupsRequested = "#form.account_signup.groupsRequested#";
   int groupsRequestedArraySize;

   int groupCounter = Integer.valueOf("#variable.groupCounter#");

   String[] groupsRequestedArray = groupsRequested.split(";");

   String group = groupsRequestedArray[groupCounter++];

   WorkflowManager wm = (WorkflowManager) pluginManager.getBean("workflowManager");

   
   wm.activityVariable(workflowAssignment.getActivityId(),"group", group);

   // This line above throws already error since workflowAssignment is null

   
   wm.activityVariable(workflowAssignment.getActivityId(),"groupCounter", String.valueOf(groupCounter));

   
   

   if (groupsRequested != "") {
       groupsRequestedArraySize = groupsRequestedArray.length;
   } else {
       groupsRequestedArraySize = 0;
   }

   int groupCounter = Integer.valueOf("#variable.groupCounter#");

   
   //LogUtil.info("Value of groupCounter             : ", "" + groupCounter);
   //LogUtil.info("Value of groupsRequested          : ", groupsRequested);
   //LogUtil.info("Value of groupsRequestedArray     : ", Arrays.toString(groupsRequestedArray));
   //LogUtil.info("Value of groupsRequestedArraySize : ", "" + groupsRequestedArraySize);

   
   DecisionResult result = new DecisionResult();
    
   if (groupCounter >= groupsRequestedArraySize ) {
       result.addTransition("noGroupUpdate");
   //    LogUtil.info("Value of Transition             : ", "noGroupUpdate");
       
   } else {
       result.addTransition("groupUpdate");
   //    LogUtil.info("Value of Transition             : ", "groupUpdate");
   }
    
   result.setIsAndSplit(true);
    
   return result;

   I checked the same code in a tool and not inside a route bean. It works there. So it seems, that workflowassignment is not propagated to the route bean but only to a tool bean.

   I cannot think of any reason why this should be a feature and not a bug.

   Anyway by splitting the code into a tool and a route it is possible to work around it.
