As part of my drools-scala project I am implementing evalators for scala
collections. This means that the some default evaluator operators like
"contains" and "memberOf" need to be overridden. My problem is that drools
seems to load the evaluators as defined in meta-infa/(I forget the file

I rewrote the rule as:

$total : doubleValue) from accumulate( Map(this["_TYPE_"] == "D",
$monto : eval(Double.parseDouble(this.get("MONTO",

I personally don't believe much in a wiki (there is a drools wiki btw),
because it gets stale fast.
I believe much more in the reference manual, which is checked in in
Subversion.
In the Drools Planner manual I 've already added "meta" information,
such as where jira is and how to build from so
I'm fairly new to this list, but I have already seen a great deal of

Hi All,
I am building an accumulator function to get the maximum value with a limit, so
for instance I have need to find the highest negative (closest to 0 without
being positive). I am calling the accumulator maxnegative, I have created the
function but can't seem to figure out how to get the
Great !
It even works with a long.
Many thanks.

To convert from string to double you have to full back to java:
Something along the lines of

Thanks for the quick response, those are great suggestions and they work as

Hi Glenn,
I'm going to start with the looping issue. The quick answer is use
lock-on-active instead of no-loop.
This is the important bit of code as far as I'm concerned:

threshold >= $averageUpdateValue) *from* $
Hi All,
I am in the process of creating some rules for a POC I am doing using drools,
having some issues understanding why I have an infinite loop in a rule.

rule "Check Parameter Threshold Update Breach"
no-loop true
when
ParameterUpdateEvent($name : n
You are right, that was the problem !
Thank you very much for your help.

If Kris' hint helps you, that's fine.
I have always used JAXB to unmarshal my XML data into a Java beans
tree, and then I walk the tree, inserting what needs to be inserted. I
feel that direct control gives me enough leeway to modify or not,
prior to insertion, etc. YMMV.
