*Description :*
I am trying to create a business process having two tasks :
a) Enter Comments Task to be entered by author and 
b) Verify comments Task : To approve or reject comments entered by author.
If the comments are approved the process will end and if it is rejected , control will flow back to user task to enter comments by author.

Approve is set in BPMN by setting a process variable : approvalStatus as 1 and for reject it i set to 0.
Eg:
 <conditionExpression xsi:type="tFormalExpression" language=" http://www.java.com/java http://www.java.com/java" >
return approvalStatus.equals("1"); 
</conditionExpression>

*Problem:*

While starting the process, approvalStatus is set to 0 intially as :
            Map<String, Object> params = new HashMap<String, Object>();
            params.put("approvalStatus", "0");          
         // start a new process instance
            pi = ksession.startProcess("com.sample.bpmn.comments",params);


I am then trying to set the process variable as 1 or 0 (depending on approve or reject) inside the code , but the same is not happening.
*Can anyone please tell if I am missing something or is there any other way to do so?*

*Code Snippet:*

//Some Code here.....................
   String approvalStatusValue="0";
   if(isCommentsApproved)
              approvalStatusValue="1";
  else
      approvalStatusValue="0";

                Map<String, Object> results = new HashMap<String, Object>();
                results.put("approvalStatus", approvalStatusValue);
                ContentData contentData = new ContentData();
                contentData = new ContentData();
                contentData.setAccessType(AccessType.Inline);
                ByteArrayOutputStream bos = new ByteArrayOutputStream();
                ObjectOutputStream out;
                try {
                    out = new ObjectOutputStream(bos);
                    out.writeObject(results);
                    out.close();
                    contentData = new ContentData();
                    contentData.setContent(bos.toByteArray());
                    contentData.setAccessType(AccessType.Inline);
                } catch (IOException e) {
                    e.printStackTrace();
                }


                taskClient.complete(task1.getId(), "mary", contentData, taskOperationHandler);

Thanks and Regards,
Sandeep
