Currently, my findings are that this is not possible? I would like to use the DataViewList widget in a form that is used in a DataViewList widget on a different page. When I try to do this, however, all I get is a progress bar that never moves past approx. 20%. What I am looking for is a way to list certain objects (Events), but for each entity also list a set of other, associated objects (Workshops). Ie: Event 1 Workshop 1 Workshop 2 Event 2 Workshop 1 Workshop 2 EDIT: I have managed to get a DataViewList inside a DataViewList working. I was probably too strict with my Xpath and it seems the widget does not provide front-side warnings when the max. number from the properties is exceeded.
