Can old workflow instances execute new code?

[Alfano, Judy (ISO)]

Hi All - We have a custom workflow that initially sends an error
notification to users, followed by a loop wherein each time the deadline
is met it checks some criteria and decides whether or not to escalate
the notification to the next level of folks. Currently we have 1000's of
these escalating daily in production due to invalid triggering event
container data. So far, support has been unable to identify the
circumstances that are resulting in the bad event container data. As a
workaround I decided to insert a condition step that checks for the
invalid scenario, and if found change the workflow status to complete
and exit. I put this new condition step in the loop thinking that as the
next deadline was met for each in-process workflow, it would find the
error and complete the workflow, taking care of the cleanup of the mess
in production. I purposely didn't generate a new version when I made the
change, thinking this would cause the in-process instances to hit the
new step the next time the loop looped.

 

This worked as I expected in our development client where the change was
made, and in another DEV client after I executed SWU_OBUF. But when I
transported the change to the QA environment, the in-process workflows
continue to execute the loop as it was before the code change. I
executed SWU_OBUF, probably unnecessarily based on the last
synchronization time - didn't help. 

 

Was I just wrong in my thinking that by not generating a new version of
the workflow, in-process instances would begin executing the changed
code the next time they hit the loop? 

 

Thanks very much for your help!
