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

You can do this using the extends keyword in your rule.
You can't use extends in the rule header.

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.

Hello
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
Max
Hi,
I`m experiencing the same problems as Vishal. I am using Eclipse 3.5
and newest
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 ) )
Please note that
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).
Edson,
Thanks for clarifying this. I appreciate it.

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,
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

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 :)

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
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 (

On the general issue, is it received wisdom that it's better not to insert
map objects direct, at least for now until map support is fully there - or
is it 6 of one / half a dozen?
Maps are data structures, not Domain entities.

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).

Btw, this brings me to a new syntax question for the default Drools rule
syntax. Is this possible:
when

eval( m.get(type) == Point, $x :
