Re: [Jason-users] Create a timer based on seconds in Cartago

[Burak K. <bbu...@gm...>]

Dear all,

Sorry for my often updates, I just tried the commit() function which leads
me to incrementation of the belief mytask, but this time again I encounter
the problem as follows:








*java.lang.IllegalMonitorStateException at
java.base/java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.signalAll(AbstractQueuedSynchronizer.java:1487)
at cartago.Artifact.commitObsStateChanges(Artifact.java:551) at
cartago.Artifact.commit(Artifact.java:629) at
example_JaCaMo.MyTimer.save(MyTimer.java:66) at
example_JaCaMo.MyTimer$1.run(MyTimer.java:42) at
java.base/java.util.TimerThread.mainLoop(Timer.java:556) at
java.base/java.util.TimerThread.run(Timer.java:506)*

Thank you.

Best regards.
