I have a groupx field which I use to create generic questionnaires. I want to log changes, which I tried to achieve by storing the original values son encoded to a session and compare them to the new values when they're stores. I tried both BeforeStore and AfterStore to create a son encoded list of new values but the Form property is not available for the BeforeStore and AfterStore plugins. I checked this with JDump. Is this a bug or a feature? And is there an alternative way to create an array or list with the form values, before they are stored so I can compare them to the original values?
