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

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

Hi,

I deleted the signal and decided to move on with belief addition. However,
it only updates the value from 0 to 1 once. I think as the operation still
goes on because of timerTask, it does not update the observable property.
In the book, I saw that commitObsState was proposed, but I haven't been
able to see any detailed example of usage. Also, I have only seen
commitChanges() in the version that I use.

Best regards.
