[Flow] Re: How to update aggregates with a single form

[Sil via]

Hi,
I had exactly your problem and I didn't find any solution but using repositories for each class. Does someone know how to manage editing of aggregates properly? Are there examples?
Do I have maybe to delete the entire collection and re-create it again?

Thanks
