Changing a wait event's key

[Michael Pokraka]

Hi all,
Is it possible to change the object key of a wait for event step? 4.7/620
system, the container element I'm using for the wait step has the correct
key in the workflow, but the terminating event that gets triggered has a
different key.

Hmmm, more detail required I guess: It concerns those nasty little things
called WBS elements which can have either an internal or the external number
or both as the object key - all referring to the same object.

Now, the flow is triggered using both keys, but the terminating event only
has the external number (comes from outside the system).

So we have BUS2054 with key INT1234EXT1234 and I want to wait for event
BUS2054.BLAH with a key of INT1234 in the instance linkage.
I've a few ugly workarounds, thinking pseudo-events which get the full key
and fire off a second evt, or a custom object with half the key in the
container and the likes, an second RFC call to get the full key beforehand.
But that's all too much sledgehammer-walnut-ish and I can't help wondering
if there's something simpler.

Any ideas welcome,
Cheers
Mike
