I have intermediary timer events after an event-based GW, together with message events. The message events are fired and they successfully attract the process to their path, but timer events - not. Specifying frequency has no effect. Specifying Timer Cycle gives
The value entered for attribute "Time cycle" of event "......." in model "......" does not comply with ISO 8601. Therefore it cannot be interpreted during simulation. For the attribute to be interpreted during simulation, enter a time span in format P[n]Y[n]M[n]DT[n]H[n]M[n]S in compliance with ISO 8601, where P = information that a period follows; Y = years; M = months; D = days; T = separator between date/time; H = hours; M = minutes; S = seconds. [n] indicates the corresponding number. Example: P6DT5H stands for 6 days and 5 hours.
And I get this message although I have strictly followed ISO 8601. Then I just place P6DT5H from the example as Time Cycle of my event. And then I get the same error message.
What am I doing wrong?
