Re: [Jason-users] JADE integration

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

Hi Bourdil, you are right in your analysis of the problem. I am working on a solution for that — that is in the java level, not .asl. 

I hope to come back soon with a solution. 

Best,

Jomi

ps.: Indeed, the block() is executed after the answer from the environment is received… So I do not know why the agent is being waked … I guess previous versions of JADE worked differently (the versions we used to develop the JADE infrastructure)…. Again, I need to investigate it further.
