SUMMARY The "FormSwitchDelegate" does not change its "checked" value when bound to a changing property STEPS TO REPRODUCE 1. Set "checked" to a property that can change (i.e., has a "*changed" signal) 2. Change that property 3. "checked" value does not change EXPECTED RESULT As with a "SwitchDelegate" from "QtQuick.Controls", the value of "checked" should be updated. As far as I remember, the "FormComboBoxDelegate" had the same issue while the "ComboBox" of "QtQuick.Controls" worked as expected too.
