Hi guys,
Thanks for the response.
When I store data as a collection the rules don't seem to get fired. I think the data
is not being read.
I tried everything suggested.
So broke down the data storing them as individual java bean objects.
Is this a possibility??
Rule
When
$fire : Fire(room != null, status == true)
$sprinkler : Sprinkler(room != "")
Eval($sprinkler.getRoomId == $fire.getRoomId) //this doesn't work. Anyway I
can compare 2 values in my rules????
Then
Modify($sprinkler){
setSprinklerStatus(true);
}
I am trying to check if the fire for the room 1 is true then if sprinkler for that room
exists then that is also set true.

When you update your objects, do you notify the session of the change?
If you do that, you should not take care of salience. The objects insertion
order is not relevant (or, at least, marginally).
To notify the session of an object change, you should either put your
modifications inside a 'modify' block (see the docs) or let your java beans
include a 'PropertyChangeSupport' field (see dynamic facts).
In your sample, when the room gets the 'fire' status, the session should be
notified of the change, and the sprinkler rule will fire.

Hi,
If you have multiple rules where its important that rule 1 be fired on the
data first and then rule 2 how can we do this without specifying the
salience factor?
I do not want my rules to be dependant on each other as the data I am
passing differs from each other.
Ex:
Room{
Name, Id,
Status,
}
Fire{
Room,
FireType}
Sprinkler{
Room,
SprinklerType
status}
I pass all data above into my working memory.
I have rules:
Rule 1: ?if fire exists update room status to ?fire??
Rule 2: ?if room has status ?fire? update sprinkler status to ?room
number??
Now when I pass my javabean objects: if theobject of type sprinkler gets
processed first it will never get the room number even if actually the room
has status ?fire?
If I specify salience feature then It will never work for my sprinkler
objects and always be multichained.
I don?t want chaining between my rules.
Any suggestions???
Thank you
M
