I have a class Customer.java with class variable "allTradeAmounts" and<br>
<br>
I have two rules as follows:<br>
<br>
rule "rule 1"<br>
when<br>
$c : Customer();<br>
then <br>
<br>
$c.setAllTradeAmounts($c.getAllTradeAmounts().add(1000)); <br>
System.out.println("after modify: "+$c.getAllTradeAmounts());<br>
</blockquote>
how does the engine know this has changed? call:<br>
update($c);<br>
<blockquote cite="mid:34885.40429.qm@web54306.mail.re2.yahoo.com"
type="cite">end<br>
<br>
rule "rule 2"<br>
when<br>
$c : Customer(allTradeAmounts < 200 );<br>
then<br>
System.out.println("AllTradeAmounts < 200 ");<br>
<br>
end<br>
<br>
The rule 1 works fine and changes the value of this variable.<br>
My question is, although the rule 1 has changed the class variable and
I can see the result of changed variable EACH TIME, when i insert a
Customer object, why is the second rule TRUE? I have changed the value
of AllTradeAmounts and I can print it in RHS and it is more than 200,
but in LHS if I check with "allTradeAmounts < 200 " ,it is true.<br>
It must be FALSE and does not fire the rule.<br>
can someone help me? what do I do wrong in LHS.<br>
In the same rule (rule 2) if I print the allTradeAmounts it is more
than 200.<br>
sorry it is a simple question, but I m new to drools.<br>
Thanks and regards <span style="text-decoration: underline;"></span>
