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.

Subject: [rules-users] Human Task Work Item
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
