Concept for Questionnaire flow aka forward filter
We need to discuss the way we want to support forward filters. At the end this will also effect the possibilities for input filters.
The reason is the way, forward filters are modeled in DDI. The model focusses on questionnaire flow and therefore does not attache the filter information tightly to the question item that initiates the filter.
I have added a powerpoint to this issue to make this visible and also offer some kind of UI mockup. The first slide shows the simple case of a question that drives the filter directly. The second slide shows the case where the filtering happens later This means, that on one hand, there is a linkinto the filter switch for the actual flow step and there is also a link for the stearing parameter.Questionnaire-Flow.pptx
