That message is posted when the widget changes the value of the array by adding/deleting a key. It is not posted when the array is set.
Formattedheightchanged should fire when the total height of data changed. Easiest way to get it sent is expanding a node. My use of that widget never uses the changed message but I’ve made a good bit of use of the height message.
