Re: [rules-users] WorkItemNodeInstance and the on exit action
Chris,
Yes, we can only assure you the work item exists between it is triggered
and completed (or aborted). So if you want to access any data related
to it in an on-exit action or any further part of the process, it's
probably best to simply map that data to a process variable. This will
make you action code a lot simpler as well.

Hi Kris,
we experienced some troubles with our drools flow integration today
(we upgraded to the lastest snapshot) and I found out that is has to
do with a fix (see [1]) you commited some time ago.
Our problem is, that we access the data submitted by the user to
finish a human task in the on exit action of the human task node
like this:
WorkItemNodeInstance wini =
(WorkItemNodeInstance)context.getNodeInstance();
Map<String, Object> result = (Map<String,
Object>)wini.getWorkItem().getResult("Result");
This results in a NPE because the workItemId is set to -1 in the
WorkItemNodeInstance
before getWorkItem() is called. So getWorkItem() returns null.
Is there a better (recommended) way to work with human task data?
Maybe using an
out-mapping?
Thanks,
chris
