Re: M:N association refuses to work
Correcting this ...
ResultRepository.java
"
public class ResultRepository {
@Programmatic
public Result create(
final String description,
final int simulationYear,
final int status
) {
final Result result =
container.newTransientInstance(Result.class);
result.setDescription(description);
result.setSimulationYear(simulationYear);
result.setStatus(status);
return result;
}
}
