Passing Map to tasklistener expression method in workflow

[monika]

I am using a method in my expression of activiti:tasklistener which is taking Map<String,Object> as a parameter.
Instead of passing this map inside the initail variable map, i want to create this map inside the workflow itself and want a way to edit and update its variables also inside workflow.
Is there any way to do this through activiti?

The code snippet is as below:

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:activiti="http://activiti.org/bpmn"

   xmlnsmgdi="http://www.omg.org/spec/DD/20100524/DI" typeLanguage="http://www.w3.org/2001/XMLSchema"
   expressionLanguage="http://www.w3.org/1999/XPath" targetNamespace="http://www.activiti.org/test">
   <collaboration id="Collaboration">
      <participant id="pool1" name="Pool" processRef="process_pool1"></participant>
   </collaboration>
   <process id="TestProcess" name="Test Process">
      <startEvent id="startevent" name="Start"></startEvent>
      <userTask id="ApprovalTaskForManager" name="Create approval task"
         activiti:dueDate="${dateVariable}">
         <extensionElements>
            <activiti:taskListener event="create"
               expression="${approvalTaskListener.processApproval("approvalActions")}" />

         </extensionElements>
      </userTask>
   </process>
</definitions>
   


Here my ("approvalActions") is a map which i dont want to pass in the initial variable map rather want to create in workflow itself. is there any way to do that?

Just to get it straight, you want to:

1. Use a map as a process-variable. Later in your process, you can do Map<?,?> myMap = (Map<?,?>)execution.getVariable("mapVar");

or

2. Use a map to fill process-variables. This means, every entry in the map represent a single process-variable in activiti.
