Re: [rules-users] drl execution problem
e.g. add an ID field to Person that is incremental in value on subsequent "people" person1: Person( $firstName1: firstName, $id : id ) person2: Person( firstName != $firstName1, id > $id ) This ensures only one match of person1 and person2 will occur, not person2 and person1.

Re: [rules-users] drl execution problem
Hi laune Thanks for the solution. but i am confused a bit with point (b). how to add a constraint asserting an ordering between Persons in drl. sorry it may seem silly Qs but i'm new to drools and really want to know that.

Re: [rules-users] drl execution problem
You have, say,
Person( "Joe" )
Person( "Jim" )
This happens:
person1 <- match any Person: (1) match Joe, and (2) match Jim
person2 <- match any Person name2!=name1: when (1) then match Jim,
when (2) then match Joe
To avoid this, you can
(a) retract person2 in rule "FirstNameDifference"
(b) add a constraint asserting an ordering between Persons, e.g.,
some unique number
(c) use compareTo with names, test for -1
(d) post-process dataDifferenceVO.getDataDiffArray()

Re: [rules-users] drl execution problem
I suspect Person 1 and Person 2, plus Person 2 and Person 1 are matching.
Try putting a sysout in the RHS showing the people matched to confirm.

[rules-users] drl execution problem
i have one drl like below:
rule "FirstNameDifference"
no-loop true
lock-on-active true
when
person1: Person( $firstName1: firstName )
person2: Person( firstName != $firstName1 )
then
dataDifferenceVO.getDataDiffArray().add("Person/FirstName");
end
i'm passing a list of objects in which i have 2 person type objects. my aim
is to check if the firstnames are same or different. if its different i need
to add one String to the DataDiffArray that is declared inside
DataDifferenceVO class.
but as i pass 2 person objects in the WM the rule is getting executed twice.
i.e, the string "Person/FirstName" is getting added twice in the array list.
why is this happening?... the rule should compare 2 firstnames and return
one String...is not that?... what step should i take to achive what i
want
Thanks a lot i advance... :) :) :)
