Hi Christopher,
I could see the early stop only once with your workflow, in which case
only 9 from 10 tokens arrived at the end. Since then it seems to be warmed
up, as never more behaves incorrectly.

When I replaced the Test for Display, I got bad results more
frequently (1 from 4-5 runs), with 5,6,7 tokens out of 10, resp.

Hi Norbert,
I modified your example slightly and added it as a test as
ptII/ptolemy/domains/pn/test/auto/Branching-switch-PN-ptolemy.xml
I can't get this to fail though.
I'm running under Java 1.5.0_06 under Windows with the Ptolemy CVS
tree.
I changed the Sleep actor to 0L and I always get 10 outputs.
I've left a copy of what I checked in at:
http://ptolemy.eecs.berkeley.edu/~cxh/models/Branching-switch-PN-ptolemy.xml
If you have a chance, could you download that version and try
replicating the error?
Also, what version of Java and what OS (Linux? Windows?) are you
running.
If you let me know via email, I'll summarize to the list once we get
to the bottom of the problem.

Hi,
I have created a small workflow to demonstrate the Switch actor. A Ramp
produces numbers 1..10, an Expression produces 0..2 (input mod 3), and the
Switch has three channels, each with just one Expression to produce a Strin
g.
Finally, the three branches are brough together with NondeterministicMerge
and
the strings are displayed.
So there I expect 10 strings as output, which is mostly the case if I run i
t.
However, sometimes - quite frequently - less strings are displayed (tokens
somewhere are lost) when the workflow stops.
The workflow works nicely if I do one of the followings:
- replace NondeterministicActor for Select
- put a Sleep with 1ms to slow down the execution
So it seems to me that PN senses termination condition wrongly in the origi
nal
case. Or what else?
I attach the workflow, already with the Sleep, so it works as expected.
If you delete the Sleep actor (or even just set to 0) and run it a couple o
f
times, you will see shorter outputs occasionally.
I would like to understand what is happening and why (except if it is a bug
).
Thanks in advance for explanation.
