[kepler-dev] Controlled actors order in PN(?)

[Efrat Frank]

Hi all,

In the attached workflow I'm using 2 variable setters to update the 
value of the same parameter. I'm updating the variable twice so that if 
the lower part of the workflow fails, the output variable will hold the 
value of the upper part (see image). But, if both parts run successfully 
they race over which is going to update first..  This workflow cannot 
use SDF and when using PN, I cannot guarantee that 'Variable Setter 2' 
will execute prior to 'Variable Setter 1'. Since this is a sink actor, I 
can't use triggers either.

Is there a way to decide this race in PN? Could it be solved using a 
different director?

Thanks a lot,
Efrat
