Hi, I am trying to compare date in condition of rule. I set the date format
in system parameter.
System.setProperty("drools.dateformat", "dd/MM/");
When I get the date from the fact object directly, it works well.

I'm not sure whether they were added or not. I noticed the rules weren't
running when I expected them to though, so perhaps not. I have worked around
it by putting all my rules in the same package - luckily I only had about 30
different rule files, but it is a less than ideal solution.
Once I have
Someone mentioned me the problem some time ago. I have a fix for it in my
local repo, butI was waiting for the trunk to be stable to test it.

I am trying to use a Knowledge Agent in 5.1.1 with a change set with a few
different packages and resource types in it, and I am running into a problem
where it is not adding all the packages. Looking at the code I can see that

Hello,
I am using sliding windows in the form:

expected Drools to infer from the window length that all events on EP1 apart
from the latest one can be retracted, is this
Sorry to not include this earlier, but the exeption (where I am developing on
another machine) disappeared before. It is exactly:

and my .dslr file has exactlly 16 lines.

I have some more incite into what might be causing the problem. Once I
remove the drools.package file - which shouldn't be needed since the imports
and expander are in the .dslr file - and have a trivial example - I can see

Please let me re-emphasize something from my e-mail: "for the general

Unless you are having performance problems for your specific use case, you
should not be worrying about this, as the engine is optimized for th

but not if I generalize it:

Hi all,
This is a very interesting discussion, so I re-read the Drools Flow manual.
IN section 8.1, it is stated as one of the reasons to use rules in your
process:
Performance: Rule evaluation is optimized.
How do I have to understand this? Does rule evaluation only happens for the
rules that a
Given that facts (after some common initial processing) fall into two or
more classes that should be processed with significantly different (although
not necessarily disjoint) sets of rules and also given that the fact and/or
rule number is prohibitive for processing according to the simple design
That's probably the best way to go. I think it's a case of experimentation to
work out what runs best (and please report your results). Things to consider
are what order you have the conditions in the rules (the control fact first is
probably most efficient but may be worth comparing with it at
ok.
So the only way to do that is to add a control fact, and update it at
runtime...
Do you think that using the "control fact" method will speed up the
execution time for a large ruleset that have different ruleflow-group ?
My feeling is yes, especially if "first" rules does many updates, but I
The thing to remember is that fact evaluation occurs at object insert/update
time, not at the point you call fireAllRules. Salience, Agenda and rufeflow
control on the other hand are runtime conditions which control which rules are
actually activated in what order.

And what about ruleflow-group ?
There is no network filtering for that too ? The ruleflow-group behaves
like an agenda filter, but still evaluate all nodes ?
Could we imagine setting "tags" to nodes, and stop propagation for node
that does not declare the current task tag ?

ok?! Should i file a JIRA?

The algorithm as is does eager evaluation, as for the general case that
is still better than doing selective evaluation.
If, in your case, the decision of which rules to fire is an arbitrary
application decision, and not based on the actual constraints of the rules
themselves, then the only
Hi,
Having the same questions you had, I played a bit with agenda-groups to see
if there was any notable performance effect.
I added 200 extra rules which did not fire at all and did two "series" of
rule executions. Once with all rules within the same agenda-group and once
with the 200 extra rule
Guys, please any thoughts?

Hi, you are probably missing the drools runtime configuration.
Check in your setting tab and look for the Drools settings to see if you
have it configured.

Just wondering.
But what about Android ?
Does anyone already make drools work on it ?
