Master/Detail and specialization

0
Hi ! I have a master / detail view as it is here : https://atlasdesignsystem.mendixcloud.com/p/masterdetail Although I have several issues : detail are specializations → how can I do that, while the dataview doesn’t support specializations? when the users selects another item, he leaves the current detail to open a new one : the data is not commited which is okay. But : how can I display a confirmation message saying “are you sure you want to cancel your changes?”  how can I cancel is he says yes ? cause I couldn’t find a way to execute a microflow at this point → the next time he comes back on this (uncommited) item, he can still see the data he set before, which leads him thinking it was saved … Thx !

No idea, my best guess would be using javascript by adding the HTML-widget to your page and make that javascript adding a OnLoseFocus to some element.
