Hi,
I am new to Drools. Can anyone help me with an example of Drools in

No. Just requires developing a set of classes to work with maps. Being

ooops... correct version:

Map( this["type"] == "Circle", this["x"] == $x )

Oh, I did not intend it to sound like nit-picking.
I will skip the first half of your e-mail as I am not sure what were the

Btw, this brings me to a new syntax question for the default Drools rule
syntax. Is this possible:
when
m:Map()
eval( m.get("type") == "Point",
Thank you for your suggestion Maximiliano, debugging really works in Eclipse
version 3.4 for me. So the problem is probably in compatibility with 3.5
(but maybe just on few specific configurations).
Bye

Hello everyone,
Currently, the validate functionality ensures that rules have proper
syntax.
it is possible to extend this functionality so that business use cases might
also be validated? Is there an API/examples to do that.
For eg, in our domain, an object X can be evaluated for 3 criteria (
Thanks again Edson. I'd just used a String object to try a simple test but of
course your example makes a lot more sense. And thanks also for clarifying
that there's full syntax support in the latest mvel jar version.
I know this is a Drools rather Java list but as I'm new to both, may I ask
furt
Just remember that doing it this way alleviates the author of the rules from
having to add that "book keeping" when creating new rules. This may not be a
*rule based* solution, but it is a *Drools* solution :)

Thank you Dave. I had a look, but it seems I'd still have to track it and
process the results in Java rather than using rules, so I guess I'll stick
with my original Java solution. Unless there's some way to track it in
Drools?
Cheers

Greg is right if you want to keep it just using expert features.
Now if you model your Singleton as an event, you could use the timestamp
instead of create a specific attribute for that:
oldSingleton : Singleton( $id : id )
newSingleton : Singleton( id == $id, t
Edson,
Thanks for clarifying this. I appreciate it.

Sometimes this is indeed not clear, so I will try to explain here. Drools
uses MVEL to resolve some expressions and semantic code. Although we would
like to make it 100% compatible and enable it to use mvel everywhere, that
is easier said than done (but we do have someone working on that).

Remember that "collect" is a simplified form of "accumulate". So when you
can't achieve what you want with collect, first thing you should look for is
accumulate.
$list : List() from accumulate(
$foo : Foo( ) and not Bar( id == $foo.id ),
collectList( $foo ) )

I have the same problem when debuging rules using eclipse 3.5, drools 5.0 and
jdk 1.6.
I downgraded to eclipse 3.4 and worked for me.
Is there a solution to let me debug using eclipse 3.5?
Thanks

Maps are data structures, not Domain entities. Using maps as domain
entities is possible, but usually makes your
Take a look at the *AgendaEventListener*. It allows you to get callbacks for
when a rule has fired. This would allow you to keep track of which rules
fire along with the objects that caused it to fire.

You can't use extends in the rule header.

Hi, ta very much everyone for the help so far.
Another question - how to sort by number of matches please?
Say I have objects A, B, C and D and rules 1 to 5. Each object can match
each rule independently e.g. A can match rule 1 and 2, B might match all
rules 1 to 5, C might match none, D rules 3
24 matches
