EntityView query results in duplicate results

[Mobe91]

With approximately the following entity view, the result list contains duplicate DocumentView instances if there is more than 1 workflow entry for a document version.

@EntityView(Document.class)
public abstract class DocumentView {
   @Mapping("currentVersion.workflowEntries")
   public abstract List<WorkflowEntryView> getWorkflowEntries();
}
