Sorry, but I become more confused with every re-read. I think the original code is required.<br><br>I think that this is nothing but a FSM. Generally, this sort of problem should be doable without resorting to salience (except for one or two low priority ones acting as the "safety net").<br>

Hello.<br>
I'm facing some problems in drools with salience. (maybe I don't understand<br>
how it works)<br>
<br>
We have a rule that check if an import has been satisfied by the client. But<br>
we have a lot of pay methods so, when the import has been satisfied, we have<br>
to stop all the payment devices. If a payment device is in use, we can't<br>
stop it, so we send stop commands until device can stop.<br>
The problem is that if a device is making a pay process, and consumes an<br>
event, that event is never fired.<br>
<br>
Maybe I can explain better with code:<br>
<br>
<br>
rule "Pay device stop"<br>
Salience 10<br>
Try to stop the device and sends an OPERATION_IN event if can't stop<br>
(because there is a ticket inside)<br>
<br>
Machine rule<br>
rule "Operation in received witch devices not stopped"<br>
salience 10<br>
Sent stop events to all devices<br>
<br>
Machine rule<br>
rule "Operation in received with devices stopped"<br>
salience 10<br>
All ok. Finish operation<br>
<br>
<br>
rule "Ticket data read"<br>
salience 1000<br>
updates the debt for the user and sends an OPERATION_IN<br>
<br>
The pay hardware, when is reading a ticket, sent a TICKET_DATA_READ<br>
this rule has salience 100 and should be fired inmediatly but Drools is<br>
entering all time in a bucle from Operation in received and Pay stop device.<br>
<br>
<br>
Can someone give a clue about what are we doing wrong?<br>
<br>
<br>
Sorry for the english. I can post the original code if needed.<br>
Thanks in advance<br>
