Hi All,
Please some one give light on this problem. I am sstruggling to resolve this issue from last 2 days.
I am using JBPM 5.4.0 final with Spring 3.0 MVC and Hibernate 3. I followed the configuration given in
https://github.com/mswiderski/jbpm-examples/tree/master/jbpm-spring-web https://github.com/mswiderski/jbpm-examples/tree/master/jbpm-spring-web link.
Actually when i passing the values to processVariales while human task is going to completed, i am getting null values inside of the script task after the human task.(Please find the attached BPMN file).
The code i am using to complete the Human task is,
long taskId = unlockRequestVO.getRequestID();
humanTaskEngine.startTask(taskId,unlockRequestVO.getUser());
Map<String, Object> results = new HashMap<String,Object>();
results.put("muRequest",unlockRequestVO);
if(unlockRequestVO.getTaskStatus().equals("approve"))
results.put("isApproved",true);
else
results.put("isApproved", false);
humanTaskEngine.completeWithResults(taskId, user, results);
I have used the approach mentioned in the thread
https://community.jboss.org/thread/220416 https://community.jboss.org/thread/220416
But no use.
Please let me where am i doing wrong? :-/
Please let me know if any information is required.
