Hello

Please help with conditional states for fields.

Situation: 1 checkbox field with one value "A" and 2 Date fields DateA and DateB

This is working: When A is selected then DateA and DateB is visible, when A is NOT selected then DateA and DateB is hidden.

This is what I need additional: When A is not selected and DateA and DateB is hidden, then when I save form values for DateA and DateB should be empty, zero or like for date field with value 0000-00-00 00:00:00. Also this could happen at the moment when is changed field A state (before save), doesn't matter if I will lose previous value at state changing.
