KieScanner not properly updating model assets (classes) on incremental updates ------------------------------------------------------------------------------ Key: DROOLS-5955 URL: https://issues.redhat.com/browse/DROOLS-5955 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.48.0.Final Reporter: B Brown Assignee: Mario Fusco Priority: Major Attachments: LogFile.txt, RunTest.java, TestScannerUpdate-1.0.0-SNAPSHOT.jar KieScanner is not correctly applying incremental kjar updates to KieContainer when those updates include changes to "Model" assets authored in Business Central. Adding a new field to a model in business central, then updating a rule to reference that value will work the first time. If you repeat this again, adding another new field and new reference in a rule, after updating the KieContainer using KieScanner, executing fireAllRules on a new session will fail with an exception, claiming it cannot find the setter method for the new attribute.  It is expected that the KieScanner should be able to take new kjars produced from BC and consistently update KieContainers with their updates. There is no workaround for this. Please refer to the "Steps to Reproduce".  This was using 7.48.Final drools libraries and Business Central 7.48.Final but experienced similar issue before on 7.43.1.Final as well. I've attached the final kjar that caused the error, the RunTest.java containing the main method that ran the test as well as the log file.   My dependencies in maven for RunTest.java were:  * group: org.drools artifact: drools-bom ,version: 7.48.Final * group: org.kie artifact: kie-ci * group: org.drools artifact: drools-workbench-models-guided-dtable * group: org.drools artifact: drools-workbench-models-guided-template
