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: Toni Rikkola Priority: Blocker Labels: drools-tools Attachments: bpms_scesim-tickets.zip 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 The issue disappears when running Build of the project in the Project perspective.
