Hello All,
I saw this write up on creating custom work item for 'Notification'
http://docs.jboss.org/jbpm/v5.1/userguide/ch13.html#d0e3540
http://docs.jboss.org/jbpm/v5.1/userguide/ch13.html#d0e3540
Suppose in my work flow if I have two notification at two different locations. How do I
configure each to call a different work Item handler.
As per my understanding I can only call
session.getWorkItemManager().registerWorkItemHandler("Notification", new
CustomNotifyWorkItemHandler());
which applies to both the notification.How can I have something like
session.getWorkItemManager().registerWorkItemHandler("Notification1", new
CustomNotifyWorkItemHandlerOne());
session.getWorkItemManager().registerWorkItemHandler("Notification2", new
CustomNotifyWorkItemHandlerTwo());
Do need o create two custom work item's Notification1 and Notification2?
Regards!

The idea of handlers and work items is that you have one type of work item that it
presents some idea/functionality like "Notification" so i has one handler with
different parameters passed to it.
You could also make some generic notifivation handler with attribute specifing behavior
and than from that handler delegate execution to apropriate class. this is if you wont
different behavion for the same work item.

Hi, as Adam said, the mapping of a service task name to the handler implementation is
pre-configured and cannot be changed at runtime afaik. You would either create two
different handlers or have one that is smart enough to do whats needed depending on that
parameters you pass in.
Hope this helps.

Another approach could be that (of course depending on your process) you create a session
and register notification handler A then start the process that executes the notification
node then goes to a wait state lets say receive task, so you could dispose the session.
After a while you load the session and register the second (B) notification handler and
signal the process to continue its operation.
That should work since you register the work item handlers on the session upon its
creation (either a new one or after loading it from data store).
This is the flexibility that jBPM/Drools gives you but final solution is up to you. Just
my two cents ;)
