In a content-app I have multivalue field where one field is a CompositeField with a Text-Field (or other fields) and a Checkbox.
When I initially add one Field, set the Text-Field and check the Textbox and save the form both values get stored. However, if edit this Node again and disable the checkbox, the new value of the checkbox is not stored.
If I only change the textfield, the text-field's value is stored.
If I change both textfield and checkbox, both values are stored.
