Hi Amandine,

I guess this is the first time this situation is considered :-)
	— a kind of double suspension

For sure, it should be optimised. Let’s think about a proper solution….

Best,

Jomi

ps.: anyway, what a performance, 20K RC in a second!!!!!

Is it the wanted behavior of the system, to get in 20 000 RC in 1 second ?

Hello,

I have a case in which an intention 1 having a feedback action is 
suspended by another intention 2. The intention 1 was acting and got a 
feedback action, but is still suspended. The intention 2 is in a way. In 
this case, the agent is looping without any sleep, performing dozens of 
thousands reasoning cycles because canSleep=false (line 235 
CentralisedAgArch) because C.hasFeedbackAction=true. But it this case 
I'm not sure that it makes sense to check the feedback action since 
selectAction of the TS do not return suspended intentions. Is it the 
wanted behavior of the system, to get in 20 000 RC in 1 second ?

Best,
Amandine

Hi Jomi, all,

I am getting the following start-up Exception when activating the checkbox "Print out warnings about singleton variables in plans and rules" in Jason options.

Jason Http Server running on http://192.168.2.8:3272
[agent1] as2j: parsing error: "jar:file:/C:/Users/franc/Documents/jason-2.4/libs/jason-2.4.jar!/asl/kqmlPlans.asl"

[agent1] hello world.

As you can see, a dummy "hello world" project still works but I wonder if other projects might have a problem. Anyway, this option is really useful and I hope it is easy to fix.

Many thanks for all you help and support.

Fran

Hi Amandine,

you can try:

java -classpath $JASON_HOME/libs/jason-2.4.jar jason.util.asl2dot XXXX.asl

Hello,

I wanted to generate the dot file as explained here 
https://sourceforge.net/p/jason/mailman/message/29131593/ but I don't 
have the asl2dot and I don't know how to generate it. I suppose I could 
find out spending some time but if you already have the answer... :)

Hi Amandine,

Thanks again for the detailed bug report.
They are fixed in the GitHub.

Best,

Jomi

Here we can notice that the order of evaluation of hasSubsetAnnot is in reverse order compared to the previous case.
