[rules-users] decision table 'not exists'

I need to have a rule in a decision table that fires if there is no object in working memory that matches the given conditions. I have no trouble saying "is there any object that matches" using "exists" keyword, but I can't find any syntax that works for saying "not exists" in a decision table. Thanks in advance for your help! -H -- View this message in context: http://drools.46999.n3.nabble.com/decision-table-not-exists-tp3356570p335...
