This is specific to 10.0.
Up to 9.0, form view option was available according to the view_model setting in window action.
However, it is not the case with 10.0 and form view option is not available even when view_model includes it.
Because of this, it does not seem to be possible to switch to form view from an editable list view where clicking on a line let you edit the record in the current list view instead of opening the form view.
Is there a workaround which I am not aware of, or is this a limitation with 10.0?
