Hello - I have a question on how to a contains operation with primitive values. What I have is a message that has a field called intTest that is a List<Integer>. If i do an intTest contains 4 check, then check compiles but it never matches. However if I do an eval it does work. Does anyone know how to use a primitive in a contains. Here is a sample of the rule: package com.sample import com.sample.DroolsTest.Message; rule "Test" salience 9999 #when Message( eval(intTest.contains(Integer.valueOf(4)))) when Message( intTest contains 4) then System.out.println("Found 4"); end -- View this message in context: http://n3.nabble.com/Question-on-contains-operator-with-integer-tp440559p...

Yes. But the collection I am testing has Integer objects it is the object of the comparison for containment that is an int primitive. So my thoughts are if this would never work unless I use an eval then why does the rules parser allow the creation of condition that is invalid? -- View this message in context: http://n3.nabble.com/Question-on-contains-operator-with-integer-tp440559p...
