I've several number of rules. One rule has variable initialization e.g.: ... rule "AmountsAreNotNull" salience 20 when < conditions > then ... res = new Integer(a.compareTo(new BigDecimal(25))); res = (res == -1)?0:res; res = (res == -1)?0:res; res2 = new Integer(a.compareTo(b)); res2 = (res2 == -1)?0:res2; ... end The values of these variables are proper and equal 1 Then next rule has comparing for res|res2 values, but they have lost their values (res == null and res2 == null) rule "CompareValues" salience 10 when res:Integer(intValue == 0) res2:Integer(intValue == 0) result:List() then result.add(Boolean.TRUE); end What decision you can advise me to save variables value between rules? Thanks. ____________________ Regards, Komissarov Alexander mail: aleks.komissarov(a)gmail.com icq: 239128267 ---------- Пересланное письмо ---------- From: "Anstis, Michael \(M.\)" <manstis1(a)ford.com&gt; To: "Rules Users List" <rules-users(a)lists.jboss.org&gt; Date: Thu, 14 Jun 2007 15:03:33 +0100 Subject: RE: [rules-users] How to get value of global variable from one rule toanother I believe globals are to be used in the RHS of a rule and not the LHS which uses "normal" facts. I would suggest rule "AmountsAreNotNull" asserts new objects that activate rule "CompareValue" or something similar. Saving variables between rules should be accomplished using logically asserted facts. I hope this helps.

Not for reasoning and exchange of values between rules. Values that are changed by rules and are reasoned over are clearly facts of your domain and should be modeled as such.
