I am not pretty sure if this is pure Modelica. Even dymola is not able to handle this model. But maybe that doesn't mean anything. So probably we should get this running.
Note:
See TracTickets
for help on using tickets.
This is correct Modelica and does work correctly in Dymola 2013 FD01. This functionality is important for supporting the Modelica Petri Net Library PNLib!
