Re: OSWorkflow - initial action forsteps?

I like the idea of having auto-transitions, but does it make sense to
"auto"-call more than one action? I think you should use a split, if you
want to perform more than one action in parallel.

If there was a "step initial function" in the form of a pre-function,
would it be executed every time you make a transition to the same step
from within an action? If yes, this could be what you wanted, or not.
The same is true for "step post functions".

I vote for the proposal that Alex made. It would be great to have all
actions with attribute "auto=yes" performed automatically.

This sound really good and is what I would like to see soon :-)
However it is limited to a single "autoaction" per step which sometimes

is not enough.
Why not have an "auto" attribute for each action? When a step becomes
current step all actions with "auto=yes" will be performed
automatically
with regards to the normal condition/restriction behaviour.
