Re: askOne and multiple agents

I thank you :) (and sorry my english...)

I have used this version...

But I have tried the .asl:

[code]

// Agent sample in project TaskAlloc

/* Initial beliefs and rules */

/* Initial goals */

!generateA.

//!sendIt.

/* Plans */

+!generateA:.my_name(M)<-

+a(M);

.wait(100);

!sendIt.

+!sendIt:.all_names(AGENTS)<-

.send(AGENTS, askOne, a(_), LIST);

.print("List is: ", LIST);

+list(LIST);

.

[/code]

And I only receive the first answer of receivers :/

I looked the code and i think the problem is in TansitionSystem.java@238 line:

[code] if (send.getTerm(0).isList()) { // send to many receivers [/code]

the term in position 0 (when I run the asl code) is of VarTerm class and does not a "List" term.

If I use the .send internal action in this way:".send([a,b], askOne, a(_), LIST);" it work because I use a explicit list. :(

Well, is there one way to I use the .send with VarTerm? I need it because in my problem I do a pre-proccess in the  AGENTS list to select a sublist to send the askOne message.

best regards....

Hello Marcos,

the latest version of Jason (1.3.5), just released, supports synchronous ask with several receivers. All the answers are collected into a list. For instance, in

       .send([b,c],askOne,vl(_),L)

L will unify with

       [vl(1)[source(b)],vl(2)[source(c)]]

HTH,

Jomi
