Weird human task behaviour
by HMandic
I have this strange problem, when I call
int taskId = 105; // dummy taskId, the real one is obtained
through TaskSummary
BlockingTaskOperationResponseHandler b = new
BlockingTaskOperationResponseHandler();
client.complete(taskId, "myusername", null, b);
while (!b.isDone()){
b.waitTillDone(100);
}
System.out.println("Completed task "+taskId+" owned by user
myusername.");
I get this in the log:
INFO [STDOUT] Completed task 105 owned by user myusername.
INFO [STDOUT] Notification of completed task 104
...and about 50 milliseconds later...
INFO [STDOUT] Notification of aborted task 104
No error messages between these two notifications.
I understand that these ID's are not the same because 104 is actually
workItemId that holds taskId 105.
The status of task 105 in the database table "task" is "Completed", but the
workflow stops after it and I can't do anything about it.
Is there any known issues with task persistence in JBoss 5.1 or something?

Re: [rules-users] drools-server empty response body
by lhorton
In my test, I posted the set-global command along with the rule execution
commands, like this (snippet):
List commands = new ArrayList<Command>();
commands.add(CommandFactory.newSetGlobal("logger", logger));
commands.add(CommandFactory.newInsert(fact, "outId"));
commands.add(CommandFactory.newFireAllRules());
BatchExecutionCommand batchCommand =
CommandFactory.newBatchExecution(commands, "ksession");
.....etc.
(I had configured the ksession as stateless)

Re: [rules-users] drools-server empty response body

you'd do something like this... in your Java code, instantiate an instance
of your logger (of whatever class)
import org.apache.commons.Log; // or whatever logger class you are using
private Log mylogger = new Log();
then create your command list and add the logger instance as a global:
List commands = new ArrayList<Command>();
commands.add(CommandFactory.newSetGlobal("logger", mylogger));
then in your rule you declare the global:
global org.apache.commons.Log logger;

Minimax Planning
by Chris Spencer
How would you use Drools Planner to decide moves in a zero-sum
complete information game like Tic-Tac-Toe, Chess, Go, etc?
I understand how algorithms like Minimax are used for this, and I can
see how I could build a solver to calculate legal moves as well as the
fitness of each player's position after N hypothetical moves, but I'm
not sure I see how Planner could aggregate the scores of arbitrary
plans to find the action corresponding to the minimum/maximum score at
each step.

Planning Under Uncertainty
by Chris Spencer
Hi,
Does Drools Planner support uncertainty / probabilistic planning? I've
Googled, and only found a single reference, in the form of a research
paper, "Reasoning with Uncertainty in Drools", which doesn't even
appear to be publicly downloadable.
If not, how difficult would it be to add?
Regards,
Chris
