<div dir="ltr">Obviously I can.<br>Thank you very much David for you motivation to help.<br><br><br>Here is the relevant set of rules as it's looks in My Drools3 .drl file: (Please see comments after the drl).<br><br>"""<br>

<br>What I'm doing now is first location all the AgeGroup objects that match the subscriber and then check (for each) of the groups is it matches the campaign collection.<br><br>Please again note that I'm using Drools 3, we're considering here Drools4 but for now It's hard core 3.<br>

Could you write out the rule(even pseudo-code if necessary), or the something as to try and clarify what you are trying doing? <br>

<div dir="ltr">Thank you very much for the fast and accurate reply David,<br><br><br>Is it also possible to use the opposite positioning?, something like:<br><br>Subscriber($age : age)<br>Campaign($campaignAgeRangs : listOfAgeRangeCodes)<br>
AgeRange(minAge <= $age, max >= $age, $campaignAgeRangs contains code)<br><br><br>Please don't try the above as this tries to create a field extractor for $campaignAgeRangs on the AgeRange object which fails for obvious reasons..<br>
<br>I would like to to filter first by Subscriber, then by Campaign and last by age range. This is obviously a simplification of the actual filtering rules.<div><div></div><div><br><br><br><div class="gmail_quote">
