I would like to build a form that has some kind of overview at the top, where the user defines a list of items (repeating grid). For each item, there should then be a section further below (repeating section) where the user needs to add additional information to that specific item (it's A LOT of information, that's why I need a whole section per item and can't just add additional fields in my repeating grid).
So the easiest way would be to let the user manually add a section per item, but that's not very user friendly and also I need to make sure that there is exactly 1 section for every item.
I tried using count($my-item), count($my-grid) and count(xxf:repeat-items($my-grid)) as the min and max iteration count of my repeating section, but neither work. Also when I add $my-item as the calculated value of the first text field, always the first item in my grid is taken (should be the i-th, i being current iteration count).
Demo here (should be self-explanatory): http://demo.orbeon.com/demo/fr/orbeon/builder/edit/92384bdcfd5dfeef2f79e79540e566501e6e5243
How can I achieve this?
Orbeon Forms 2018.2 will have a component to automatically synchronized repeated content. See the documentation for details.
