Score curruption exception in drools-planner-5.4.0.CR1
by Nurlan
Hi guys!
I have some exception and I don't know why?
My rule *someRuleId* has weight *1*
2012-05-12 03:47:08,224 [main] DEBUG Step index (570), time spend
(115566), score (0hard/0soft), initialized planning entity
(SomePlanningEntity [id=21, …]).
2012-05-12 03:47:08,465 [main] DEBUG Step index (571), time spend

java.lang.IllegalStateException: Score corruption: the workingScore
(-4hard/0soft) is not the uncorruptedScore (0hard/0soft):
The workingMemory has 4 ConstraintOccurrence(s) in excess:
someRuleId/NEGATIVE_HARD:[SomePlanningEntity [id=2482309, …],
SomePlanningEntity [id=54, …]]=1
someRuleId/NEGATIVE_HARD:[SomePlanningEntity [id=2482309, …],

someRuleId/NEGATIVE_HARD:[SomePlanningEntity [id=54, …],
SomePlanningEntity [id=2482309, …]]=1
Check the score rules who created those ConstraintOccurrences. Verify that
each ConstraintOccurrence's causes and weight is correct.

Formula error in Business Rule(Guided editor)
by Manasi
Hi,
Currently I am facing following issue while inserting a formula in Business
Rule(Guided Editor):
1) I have written following formula to be executed in Business Rule(Guided
Editor):
WHEN
1.
The following exists:
There is a RuleObject [$r] with:
installations < 100
THEN
1.
Insert RuleObject:
calulatedValue = $r.installations*3
But it gives error 'Unable to analyse expression' when i try to Verify the
rule.
I want my end result will be a calculated value instead of Literal value.
Please let me know the correct syntax to use formula in this type of rule.
Thnaks.

Using "collect" repeatedly over sub-groups of a fact
by Mike Goldner
I have a single rule that includes a "collect" pattern to pass a collection
to the RHS. However, what I now need to do fire this rule for multiple
collections based on groupings defined by attributes on the fact.
Here is an example:
Fact(a = 1, b = 1, c = 1)
Fact(a = 1, b = 1, c = 2)
Fact(a = 2, b = 1, c = 3)
Fact(a = 2, b = 2, c = 4)
Fact(a = 2, b = 2, c = 5)
I would like to create sub-groups based on the attributes 'a' and 'b'. My
rule should fire three times for the facts listed above, providing the
corresponding collection of Fact.
The only solution that I can think of is to build a HashSet and add each
Fact to the HashSet using the attributes as keys. I suppose it would have
to be a nested set since I can't define a multi-valued key class within a
rule. I could then handle this HashSet in a RHS block. However, I realize
that I'm completely subverting the whole rule language
Any suggestions?
Thanks,
Mike

The drools.packagebuilder.conf directory
by Carolina Pellecchia
Hi all
I am novice on GUVNOR/DROOLS, but I defined some Drools Evaluator
functions and to make the function available to the rules engine I inserted
drools.packagebuilder.conf into user home directory. Is there different
directory to do this?
Thank you in advance,
