Didn't got a reply on the user list, hoping to get some help from the devs.
I noticed when having in a simple controller with several User Parameters
(Preprocessors) with the "Update Once Per Iteration" flag marked, that the
Preprocessors are run in reverse order.
Simple Controller
User Parameter
P XX
Q ${Q}q1
User Parameter
P1 ${P}
Q ${Q}q2
Debug Sampler
In case "Update Once Per Iteration" is marked, P1=${P}, Q=${Q}q2q1
When not marked, P1=XX, Q=${Q}q1q2
Why does "Update Once Per Iteration" reverses the execution sequence of
Preprocessors?
Is this behavior intended and somewhere documented?
