Hi , The version of Drools that I have used is 4.0.4 I have used ruleflow groups to create my rule file. It has a split node (XOR) in which I specify a constraint on which a ruleflow-group is to be selected . Insert arraylists as facts in the working memory one by one. The problem I face is that when I insert these arraylists in the same session , it doesn't evaluate every constraint in the split node . The work around I am using , it that I create a new session for every arraylist , this works just fine . But creating a new session always is an overhead . Can you please assist me with this situation .
