Hi all,
I have business process running inside the gwt-console and I need to be able
to send facts and start it from another application (a remote client). Does
gwt-console expose an API over Rest, SOAP, other, for this purpose?
Drools Server exposes such interface, but using it I will lose the

OK. You mean the behavior differs by versions. My above test in which both
rules fired was using Drools 5.1.1.
Questions:
1. "Since the lock and no-loop features are based on the fact handles, the
sometimes undesired interaction occurs."
Could you elaborate more on how is lock-on-active based
As of Drools 5.1.1, drools looks at the expression in "from" as a
black box. Every time it is executed, drools creates a new fact handle
to wrap the result(s). Since the lock and no-loop features are based
on the fact handles, the sometimes undesired interaction occurs. We
may be able to improve
Sry, i fixed this issue..
Thanks..

You explanation is very reasonable:
the engine assumes anything within $p may be changed by modify($p), although
$p.address is not changed actually.
However, I tried these rules myself and both rules were fired. Why?
According to the document, only one of the rules should fire; the other's

Yes, and if you want to use the rule engine from .NET you can use the Drools
Server that expose the Drools Runtime in REST and SOAP interfaces :)

I would appreciate if you could please answer the following questions.
1. Can you share some information on the out of the box repository? Is
it a relational database or is it an embedded database such as Berkley DB?
2. Can we make Guvnor to store the rules in an Oracle database
Another way is to keep bugging Mark and Edson to put in an else clause. :P

You've already pointed to it yourself. Rules execution should be thought of in
the same way you approach concurrent programming. Execution can (and should)
be able to happen in any order possible. Only the current logical state of
working memory should influence the next step in execution, wi
Hi,
I believe the .NET implementation of Drools is somewhat out dated.
However Drools ticks all your other requirements.

We are looking for a rules engine that has the following characteristics.
1. Supports both Java and .net
2. Provides a business user friendly UI for creating/editing rules
3. Supports versioning
4. The rues in the rules repository are accessible to both Java and
.net
I certainly do appreciate the help and fully understand no one here will be
able to give me a concrete solution without a test case. I was just hoping
that describing the behavior would jog something in someone's head which
would lead to a pointed question that may help steer me in the right

I'll elaborate on the "some code to reproduce" part:

Either you define a rule covering all "else" cases, which, in your
case, could be
rule "#catch-all"
when
$i : Item( type != 1 && != 2 )
then
retract ($i)
// do something...
end
or you do rely on salience, which, in this case is not quite so "bad practice".
It depends: if the "catch all" is t
If I have a rule like below:
rule "#1"
when
$i : Item(type == 1)
then
retract ($i)
// do something...
end
rule "#2"
when
$i : Item(type == 2)
then
retract ($i)
// do something...
end
// to handle other type of Item
rule "#catch-all"
salience -10
when
$i : Item()
then

// do somet
Wolfgang...thanks for the replyI think?
I have been doing some more testing and have observed that the test case

Drools doesn't know if $p.address.state has changed or not, all it knows is
that $p has changed - it has to assume that everything within $p has changed
(including all the states).

Thank you. I understand it now:
In the 2nd rule:
modify($p) => evaluate the 2nd rule again => re-iterate $p.address with
"from", so that Drools engine can know if there is any change in $p.address
compared with previous evaluation.
Also, the above modify($p) also triggers evaluation of the 1st ru
Below is my idea.
The rule check that there is
1) no event between E1 and E2 and
2) no event after E2
which induce that E1 and E2 are the last 2 event. I think it should work but
I didn't test it.
rule "Props"
when
$E1 : MyEvent(prop1 == "MyProp") from entry-point MyStream
$E2
In reality it doesn't return any fact, it returns each of the values currently
in the list held by the bound fact ($p).
Each time the rule is re-evaluated (due to $p changing) it re-iterates over the
list again (as it doesn't know if the list has changed or not). Drools
effectively doesn't know
