I need to do an activity with a JSF list where it is possible to add, edit and delete registered users. I had managed to make the records of new people, but when I started using cellEdit to make the edits in the records, I noticed that none of the attributes of the objects appear in the list besides the ID, and I don’t know what the error in the code is. When testing, I noticed that people are being saved in the list, but nothing appears in the datatable.

I started now in JSF and do not know what to do. Any help is welcome!
