Description Gerd Behrmann 2006-12-21 17:14:31 CET
Submitted by Daniel Karlsson on the public mailing list:

I've used the attached traffic light problem as an example in a course
for some years now. It has always worked for the Uppaal 3 versions, but
now as I wanted (had to) upgrade to version 4 some properties failed. I
have investigated the diagnostic trace, but I can't understand why they

Might there be a bug in the new version, or perhaps there has always
been a bug in my model which completely escapes me?
