Re: [rules-users] Checking for a lack of an object

How do I fire a rule if an object with certain characterstics does not exists. For example my class Foo, if I have a rule: rule "Identify Foos with values" when Foo(stringProp=="blah", intProp==5) then System.err.println("A Foo was found!"); end So how do I check for lack of existence of an object with certain characteristics I tried: rule "Flag missing Foos with values" when not(Foo(stringProp=="blah", intProp==5)) then System.err.println("A proper foo does not exist"); end I also tried: rule "Flag missing Foos with values" when not(exists(Foo(stringProp=="blah", intProp==5))) then System.err.println("A proper foo does not exist"); end _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
