Philip Usatine created DROOLS-3493: -------------------------------------- Summary: Drools Workbench execution of test scenarios hangs when rule has a bug. Key: DROOLS-3493 URL: https://issues.jboss.org/browse/DROOLS-3493 Project: Drools Issue Type: Bug Affects Versions: 7.15.0.Final Environment: Drools Workbench container downloaded from Docker Hub - 7.15.0.Final Reporter: Philip Usatine Assignee: Mario Fusco Attachments: image-2019-01-08-12-13-43-386.png In the workbench, any error in a decision table or guided rule will cause web UI to hang when running test scenarios that cause that rule to execute. Reloading the page allows you to access the web interface again, but you need to navigate back to where you were. This makes iterative development and testing extremely cumbersome. The web UI reports the following error: An unexpected error happened. Please try again in a few minutes and the 'Building and running scenario' wait spinner spins forever. (See attached screenshot). Copy error details returns the following text: {"ToSubject":"org.drools.workbench.screens.testscenario.service.ScenarioTestEditorService:RPC.runScenario:java.lang.String:org.uberfire.backend.vfs.Path:org.drools.workbench.models.testscenarios.shared.Scenario::88:RespondTo:RPC"} | Uncaught exception: Client-side exception occurred although RPC call succeeded.
