Hello,
trying as hard as I can, I am not able to do method calls within MVEL
modify block, as I can
do with Java block.
For example:
modify($p) { addDescription("aaa") }
This works in Java, but not in MVEL. I was not able to find out how to
call methods (not
set properties, which works quite w
Thank you very much for your response.

I am currently using JBoss Rules 3.0.6. Do I need to go to Drools 4.0.4 for
full fledged features.
I started my project 1 month back. If I need to use 4.0.4 version to the
existing project with 3.0.0 version, what are the things need to be done??
Thanks in Advance,

Yes it is quite possible provided that in the action part you need to set
appropriate date that the other rule expect to trigger.
ex:

when
Object1(data1 == "s")

Object2.setBoolValue(true)

Can you please tell me whether the result of one rule can trigger the
evaluation of one or more other rules.
Is there any approach for doing so in Drools??
Thanks in Advance,

I'm using pattern matching on Java objects in the when part of my rules. One
example might be:

Type.STRING, $stringValue : stringValue != "OK" && stringValue != "UNKNOWN")

Perhaps I've got my binaries mixed up. If I get the chance I'll do a clean

There is an implicit KnowledgeHelper object called "drools" available in the
RHS.
drools.getRule().getName() will provide what you need.

I am confident Drools supports what you are looking for; did you try
update() - or modify() - in the "then" part of the rule (and not in Java as
you code snippet)?
Can you explain more the need for the "computed" flag on the fact? Is the
value of a property set sometimes whilst calculated at othe
Is there an easy way to access information about the currently executing
rule (e.g. Name, salience, group) within a rule consequence? E.g.
rule "Sample Rule"
salience = 100
when
$v : Fact(name == "Test")
then
System.out.println("The currently executing rule is " +
.getName());

First, thank you for yours answers which are very clear. Your solution will
probably work. I'm just desapointed that there is no way to synchronized the
shadow with the object. That would be great for my work.

Do you need ruleflow? Perhaps this is too simple and I misunderstood.
package com.sample;
public class Test {
private Integer a;
private Integer b;
private Integer c;
public Integer getA() {
return a;
}
public Integer getB() {
return b;

Indeed, it works but I will have to use such booleans for a lot of rules.
Cause my rule flow is schematically :
compute A
compute B(A)
compute C(B)

Perhaps I may create several ruleflows, one per independant computing?

I was thinking something more like this:-

rule "rule 1 - 1"
salience 90
when
a : Test(
computed == "false",
c < 15,
d >= 75)

System.out.println("setting e to 0");
a.setE(0);
Ok, I think I understood well. I modified my business code, now I call if

wm.update(wm.getFactHandle(this), this);

But it is worse. Rules that sould be activated only once actually loop, even if
I add the no-loop clause.

In essence, yes. Have a look at "update" in the manual (and a read on Shadow
Facts will probably be useful too).

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

I guess the example is a simplification as "c" (in RHS) has not been bound
to a fact.
Anyway, that aside, do you call "update" to ensure WM knows of changes to
facts otherwise properties need to be "time-constant" which in your example
they are not.

It was my fault!
The "*not in*" sugar operator DOES WORK!!!

So...never mind. No JIRAs for it.
