Instead, use getCheckboxesDefinition(), and build our save form checkboxes from that rather than extracting them from the HTML. The ability to have non-checkbox fields there is removed, as that was never intentional and is now impossible. To avoid transient problems during deployment (old JS code cached in the user's browser receiving the new format of API responses), the old property is kept in the API response. We should remove it next week. Bug: T174613 Bug: T174686 Change-Id: I5bfca5e116fe790302c3b6ac1357e80237fb1ed2
