Can an attribute know it's calling workflow?

[Michael Pokraka]

Hi Alon/Darrell,
Interesting, these were the sort of hacks I was hoping for, but alas don'=
t
play nicely in an attribute. I also found SWO_QUERY_REQUESTER, which - li=
ke
SWE_WI_GET_FROM_REQUESTER - gets its info from memory (under different
id's).
However the swo_%invoke at least told me why it won't work: The requester=
 in
the case of an attribute is the object itself, which kinda makes sense.
(Unless I'm missing something?). Argh, so close and yet so far.
 
Interestingly enough, the attribute gets invoked twice during the running=
 of
the workflow (once at startup, and once at container operation), so that
counters any performance hit I was trying to avoid. This is a bit of a
performance-intensive bit of code. I thought attributes were only evaluat=
ed
on an as-needed basis...? Oh, well.. method it is.
 
Thanks both for your input, it's fun to go digging around the internals o=
n
occasion, but now Friday becons and I am getting too thirsty for this.
 
Cheers & happy weekend.
Mike
