Why no rule will be fired if class name and attribute name is same? Following is my drl file content: package test declare input input : String end declare output taskname : String end rule "Rule A" dialect "mvel" salience 0 no-loop when $input:input(input == "a") $output:output() then modify ($output) {taskname = "Hello"}; end But if I created a fact object of input and set attribute input to "a", it did not fire any rules. -- View this message in context: http://drools.46999.n3.nabble.com/Why-no-rule-will-be-fired-if-class-name...
