Workflow seems to just halt (possible looping problem)

[Adrian Clarke]

Mike,

Thanks for the tips - Using an until loop worked fine (so now I have an
Until within an Until, instead of a While within an Until).

Thanks also for the tip about the while being obsolete. We are currently
going through an upgrade from 4.6c to ECC6, and now I can add one more
task to my ever growing list of things to do :(

With Best Wishes

Adrian

G'Day Adrian,

Two things:
1. Try replacing 3a with a simple assignment step that sets the loop
exit value.
2. Use an until loop. While loops are dead as of 4.7 or shortly
thereafter.

Cheers,
Mike
