Hi Norbert,
thanks, I will have a look at it.
Actually, I want to implement a for loop, but the number of iterations
is unknown at implementation time (it is determined at execution time).

Hi Frank,
For me, it seems you want to implement something that I call a while
loop. I have created such constructs under PN and DDF.
You may have a look at a never finished documentation on them at:

Hi Dan,
unfortunately, I don't know the number of input tokens. It should be
known when the workflow is started, so I could add an according
parameter to the composite actor, but I wouldn't be very happy with that.
I also detected another problem. The composite actor has an input port
which receives a token that has to be used as the initial input of the
inner actor. After that, the inner actor's output has to be used as
it's input. I don't know how to realize this (maybe via 'Boolean
Multiplexor', but it's not trivial).

Hi,
A simple trick is to add a 'Sequence to Array' actor (at least if
you have a SDF director). The input is some sequence of tokens and
the output is a single array token. You could then just pull out the
last member of the array. [This only works if you know the number of
input tokens.]
