No.

Scope : the workitem. Lifetime : as long as not erased from the workitem.

No. But when you use a concurrence, there is a workitem for each
branch of the concurrence.
There are rules about how workitems are merged back (into one) at the
end of a concurrence or a concurrent-iterator (please read
http://openwferu.rubyforge.org/rdoc/classes/OpenWFE/ConcurrenceExpression.html)
Maybe your issue is about defining a field in a concurrence branch...
But I've reread your code example and the field "comp" is set at the
end of the process definition, it's thus not visible.
Your "companyDefiner" participant seems not to touch your "comp" field at all.
Sorry not to be able to help you more. I tried to reply in the best
way possible with your given input.
