<DIV></DIV>Ok, I think I understood well. I modified my business code, now
I call if<BR><BR>(wm != null)<BR>
wm.update(wm.getFactHandle(this), this);<BR><BR>each
time a properties is modified.<BR><BR>But it is worse. Rules that sould be
activated only once actually loop, even if I add the no-loop
clause.<BR><BR>I understand why they loop, assuming update = (rectact +
insert), but I dont get a solution to my problem. I just want to notify an
object changement in order to read again the properties, but I dont want
to restart the ruleflow.<BR><BR>Sorry, but I find hard to say it in
english because even in french, it's not very clear ;)<BR>

<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

<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 <

>= 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>
