Jan Stastny created DROOLS-5458: ----------------------------------- Summary: Project broken after test scenario run with possibly a class-loading issue Key: DROOLS-5458 URL: https://issues.redhat.com/browse/DROOLS-5458 Project: Drools Issue Type: Bug Components: Scenario Simulation and Testing Affects Versions: 7.39.0.Final Reporter: Jan Stastny Assignee: Daniele Zonca For a Scenario Simulation that tests DRL rule and facts having an enum property a seemingly class-loading issue occurs in Business Central. The ultimate error is in the DRL file validation: {code:java|title=DRL file} package org.jboss.qa.ba.scesim; rule "child ticket" when t: Ticket ( type==TicketType.CHILD) then t.setPrice(5.0); end {code} {code:java|title=Validation error} [KBase: defaultKieBase]: Unable to Analyse Expression type == TicketType.CHILD: [Error: Comparison operation requires compatible types. Found class org.jboss.qa.ba.scesim.TicketType and class org.jboss.qa.ba.scesim.TicketType] [Near : {... type == TicketType.CHILD ....}] ^ {code} The issue happens in given scenario: # import project # go to DRL file and run validation - succeeds # go to scenario simulation and run - succeeds # go back to DRL file and run validation - fails with the error above # go to scenario simulation and run again - fails due to the rule not being evaluated for given facts (thus Ticket.price is not set and the consecutive rules fail with NPE) The issue disappears when running Build of the project in the Project perspective.   -- This message was sent by Atlassian Jira (v7.13.8#713008)
