Hi, my nuxeo bundle contains an EventListener that reacts on some events to add additional information to my documents. Now I am in a situation where I want to reject the modifications of a user. So I added a listener reacting on the beforeDocumentModification event. I thought that it might work to use event.markRollback(). But his will result in an error page for the user after modifying the document. Is there a “legal” way to do this?

Thanks, Dirk
