[rules-users] Human Task Work Item

[Vijay K Pandey]

I don't think you can get hold of workItem directly from Task ---- the only reference Task has the workItemId.  May be you can serialize the workItem and set to the content of the Task( I don't like it) - and then retrieve it later  --- else I guess you have to get hold of WorkItemInfo and then workItem..

Also creation of knowledgesession is not process/time consuming so I don't see any harm in there

Thanks for the info.  I was hoping there was a way to get the work item via mina.  We have a client application that is communicating with the TaskServer via mina and it would be nice if you could easily get a work item that is associated with a  task instead of creating a separate knowledgesession.

I guess first you have to get hold of the "workitemid" from the task data i.e. task.getTaskData().getWorkItemId().

a)       Create a "Command" class which implements GenericCommand<WorkItem>
b)       Implement the method "public WorkItem execute(Context context)"
c)       Based on the workitem id ( set this value in your command object - constructor/setter) - get hold of the WorkItemInfo object through the entity manager  and then its workItem ----- something like this

        StatefulKnowledgeSession ksession = ((KnowledgeCommandContext) context).getStatefulKnowledgesession();
                        if (workItemId==null) {
                                    return null;
                        }
                        EntityManager em = (EntityManager) ksession.getEnvironment().get(EnvironmentName.ENTITY_MANAGER);
                        WorkItemInfo workItemInfo = em.find(WorkItemInfo.class, workItemId);
                        if(workItemInfo==null){
                                    return null;
                        }else{
                              return workItemInfo.getWorkItem();
                         }

       d) Then call the execute method on the StatefulKnowledgeSession - which should execute the above Command object and that returns you the WorkItem object.

>From the Mina client, how do you get a work item associated with a human task?

I see the Task.getTaskData(), but I don't see any easy way to get the work item as I need the work item inparameters from the mina client side.

Thanks,
Todd
