How can I allow the user to select a single/multiple item(s) from a One2Many list?
Then how can I trigger some method in the model passing the ID(s) of the selected item(s)?
The problem when using your suggested approach is that currently when I click on any item in the o2m list a form pops up showing the clicked item's data instead of simply being selected. Onchange does not get triggered in this situation.
How can I change this behavior?
