<DIV></DIV>yes, i made a mistake. its a.setE(...) and not
c.setE(...).<BR><BR>I don't call update. If I dont call update, properties of
an object are just read one time for all rules?<BR><BR><BR>

changes to facts otherwise properties need to be "time-constant" which in
your example they are not.</FONT></SPAN></DIV><BR>

<DIV></DIV>Hi,<BR><BR>I have two rules :<BR><BR>rule "rule 1 -
1"<BR> <BR> salience
90<BR> ruleflow-group "rfg1"<BR>
when<BR> a : A(<BR>
eComputed ==
"false",<BR> c
< 15,<BR> d
>= 75) <BR>
then<BR>
c.setE(0);<BR>end<BR><BR><BR><BR>rule "rule 1 -
2"<BR><BR> salience 10<BR>
ruleflow-group "rfg1"<BR> when<BR>
a : A(<BR>
eComputed == "false",<BR>
c >= 15,<BR>
d >= 75)
<BR> then<BR>
c.setE(1);<BR>end<BR><BR><BR><BR>and part of the
corresponding business code :<BR><BR>public class A
{<BR><BR> ...<BR><BR> public String
getEComputed(){<BR>
if(eComputed)<BR> return
"true";<BR> else<BR>
return "false";<BR>
}<BR><BR> ...<BR><BR> public void
setE(int e){<BR> this.e =
e;<BR> eComputed =
true;<BR> }<BR><BR>
...<BR><BR>}<BR><BR><BR><BR>so, I expected that if the first rule is
activated, the second won't be. But according to my tests, the two rule
can be fired on the same object A.<BR>While debugging, I noticed the
getEComputed method was only called once. I suppose that I should write
this :<BR><BR><BR>rule "rule 1 - 1"<BR>
<BR> salience 90<BR> ruleflow-group
"rfg1"<BR> when<BR>
a : A(<BR>
eComputed == "false",<BR>
c < 15,<BR>
d >= 75)
<BR> then<BR>
c.setE(0);<BR>
c.setEComputed("true);<BR>end<BR><BR><BR><BR>rule "rule 1 -
2"<BR><BR> salience 10<BR>
ruleflow-group "rfg1"<BR> when<BR>
a : A(<BR>
eComputed == "false",<BR>
c >= 15,<BR>
d >= 75)
<BR> then<BR>
c.setE(1);<BR>
c.setEComputed("true);<BR>end<BR><BR>But I would prefer another solution.
Thanks for help.<BR><BR>
