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

Hi Burak,
I am not sure what do you mean for “pausing” an artifact. If it is related to some “wait” operation of cartago, I do not know a way to get that state. You likely have to handle that state by yourself and send that information to your other thread.
HTH,
Jomi

In your code, the thread is created inside this block, but the signal is not running inside such a block. Maybe you can move the begin/end… to inside the “run()” method.
