Re: [Jason-users] Intention could not finish error

[Jomi H. <jom...@gm...>]

Dear Burak,

I wasn’t able to figure out the error that is happening. Is there something more in the error message? (Besides intention could not finish)

Anyway, any intention can be suspended and resumed latter. The .wait internal action can be used for that, but also .suspend and .resume. 

Maybe the idea of commitments can also help you:

HTH,

The planning mechanism is simple, various consecutive products which have IDs keep coming and the agent is trying to match these products according to their colours. It also uses IDs for comparison because agents run so fast to generate the same event (i.e same products with the same IDs).

For example product red with ID 0 is generated, then product blue with ID 1 can be generated after 2 minutes or hours. Is it possible to define a timeout for the intention? Or is it possible to await it forever etc?
