Please see discussion here: Why no refresh_data_bindings() for write back data binding?
Currently refresh_data_bindings only works to update the UI based on changes to self.item (as a whole). I’d welcome similar functionality for write backs. So a refresh_data_bindings_for_write_backs would get all relevant data in the UI and copy it to self.item.
And a distinct but related request: make data bindings available in code. I’d like to create and/or read the bindings created in the UI.
