Ruleflow only executes all ruleflow-groups one time in Stateless session after drools-server restart

Create simple rule project with rules and a ruleflow. Compile and deploy the rules to drools-server. Execute the rule engine by sending a JSON command to drools-server via cURL the first execution should work correctly. All ruleflow-group nodes should fire the second execution with the same data should fail. Only the first ruleflow-group node should fire. Restart drools-server by going to JBoss console and disable / re-enable the service. Execute the rules again and they should work correctly. Then execute again and they should fail. Detailed steps to recreate: Create a simple 3 step ruleflow. START --> Step1 --> Step2 --> Step3 --> END I have created a sample rule project for testing this issue. This was created in Guvnor 5.5. The text below is from the view source code window in Guvnor: package SimpleRuleflowTest declare Input Name: String end declare Output Name: String end declare InternalData StepNumber: Integer end rule "Step_1" ruleflow-group "Step1" dialect "mvel" when Input( ) then InternalData fact0 = new InternalData(); fact0.setStepNumber( 1 ); insert( fact0 ); end rule "Step_2" ruleflow-group "Step2" dialect "mvel" when InternalData( StepNumber == 1 ) then InternalData fact0 = new InternalData(); fact0.setStepNumber( 2 ); insert( fact0 ); end rule "Step_3" ruleflow-group "Step3" dialect "mvel" when InternalData( StepNumber == 2 ) then Output fact0 = new Output(); fact0.setName( "Finished with Step 3" ); insert( fact0 ); end I am sending the following commands to the server using JSON: { batch-execution: { lookup: "ksession1" , commands: [{ insert: { object: { "SimpleRuleflowTest.Input" : { "Name" : "Test" } }, returnObject: " false " , } }, { start-process: { process-id: "TestRuleflow" , } }, { fire-all-rules: { max: "10" , out-identifier: "firedActivations" } }, { get-objects: { out-identifier: "objects" } }] } } For my tests I am using cURL to send the commands to the drools-server. Below the cURL command line I am using to test: curl -v -H "Content-Type: text/plain" --data "{\" batch-execution\ ":{\" lookup\ ":\" ksession1\ ",\" commands\ ":[{\" insert\ ":{\" object\ ":{\" SimpleRuleflowTest.Input\ ":{\" Name\ ":\" Test\ "}}}},{\" start-process\ ":{\" process-id\ ":\" TestRuleflow\ "}},{\" fire-all-rules\ ":{\" out-identifier\ ":\" firedActivations\ "}},{\" get-objects\ ":{\" out-identifier\ ":\" objects\ "}}]}}" http: //localhost:8080/drools-server/kservice/ rest /execute* Below is the JSON returned after the first execution just after the drools server is started. Notice that 3 rules are executed and an Output object is created and returned: { "execution-results" : { "results" : { "result" : [{ "identifier" : "firedActivations" , "value" : { " int " : 3 } }, { "identifier" : "objects" , "value" : { "list" : { "SimpleRuleflowTest.InternalData" : [{ "StepNumber" : 1 }, { "StepNumber" : 2 }], "SimpleRuleflowTest.Input" : { "Name" : "Test" }, "SimpleRuleflowTest.Output" : { "Name" : "Finished with Step 3" } } } }] } } } Below is the JSON returned for every other call to the drools server after the first time. Notice that only one rule is executed and no Output object is created: { "execution-results" : { "results" : { "result" : [{ "identifier" : "firedActivations" , "value" : { " int " : 1 } }, { "identifier" : "objects" , "value" : { "list" : { "SimpleRuleflowTest.Input" : { "Name" : "Test" }, "SimpleRuleflowTest.InternalData" : { "StepNumber" : 1 } } } }] } } }
