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.

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
