> 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.
