ListView inside the ListView

I have a situation of creating a GUI in a way that I need to have a nested ListView inside another ListView.  The problem I’m encountering is that I want to allow users to edit data in both list view.  First one is not a problem, fields are editable. But the data in second list view is not editable. Is there anyway I could do this without some kind of pop-up where users can fill data?

Perhaps you could give a little more info on your setup because I just ran a little test trying to replicate what you have and everything seems to be editable. I have both listviews set to editable and the attributes set to read/write in security.
