Classes as event receivers

[Kisloff, Philip B]

Hi Mike,

Thanks for those suggestions. I've just read Jocelyn's blog, and I think
I need to explain a bit more about what I'm trying to do.

The event created is from a traditional BOR event 'assigned', from the
ArchiveLink area. Although I don't have a content repository in the
testdrive, our 4.6C production system does, and I was curious to see how
the workflow could be re-written with objects. So I can re-create the
assigned event with the object key filled in. The receiver for this
event does quite a bit of processing and only starts a workflow for
exception handling. A one-to-one replacement of the receiver function
module with a receiver class was my intention.  

I now suspect I'm trying to mix'n'match BOR and classes in the event
linkage table, which is a different question entirely!
Would be why there is no event details in the container. Perhaps it
can't/shouldn't be done.

Not got access to the testdrive system right now, so apologies for not
trying again before typing a response.

regards
Phil

Hi Phil,

It's much simpler than that. The event is not really used in the class
sense and in a workflow context isn't handled by the class, and you
don't
really need the BI_...interface (at least I've always simply entered it
directly into the linkage).

It serves just for the sake of definition. The WF system handles the
event, not the class. The object key is in an event container which gets
passed to the event receiver in the usual way.

Jocelyn has done a sterling job of describing this in great detail:

Cheers,
Mike
