Hi,
Sorry for the late answer ; I assign the issue to someone else but with the HikaShop 2.4.0 release... Well
The "entry" system was not made to work with dynamic fields ; in the way that when the entry system is duplicating a zone (the "entry fields"), it just duplicate the elements so the javascript for the initialization of advanced elements could not be re-call.
That's why the "date pickers" are not working, like the WYSIWYG, ajax file, ajax image...
I will see with the rest of the team how we can improve that for the entry system.
When I assigned the issue I though that we could fix this issue pretty fast but it looks like the resolution will take more time than that. So the issue will stay in the TODO list and I hope that it will be fix soon.
