Hello... I don't know whether it's a bug or something else... - i'm currently evaluating the new version m2 and especially the rule-flow feature, which would be the yet missing part for us to use drools. So after creating a testflow.rf with your editor i've put the created .rfm-file in the context as sugested on the blog/release-notes: processBuilder.addProcessFromFile(new InputStreamReader(DroolsTest.class.getResourceAsStream( "/testflow.rfm" ) ) ); After invoking the rules with workingMemory.startProcess("test"); and/or workingMemory.fireAllRules(); nothing happened... A look in the sources and the rfm-xml-file shows, that the element <ruleFlowGroup> is empty! I would have expected the name of the group at this point... After changing this to the desired string, the behaviour looks more expecting ;) The problem is, that the .rfm file is regenerated after editing the rf-file so changes to that will be lost... Is it a bug or did i something wrong? TIA Björn
