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

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

Dear all,

I think I solved the problem using the following option :

 this.beginExternalSession();
commit();
this.endExternalSession(false);

I will try it again in the morning. I hope the solution can help the others.

Best regards.
