Is there a 'right place' to listen for all ColumnStructuralChangeEvent fired by layers. If I register a layer listener on the table (top layer), I won't get all the ColumnStructuralChangeEvents fired. E.g. if the data layer fires a delete column event for a column that is hidden by hide/show layer, ancestors of the hide/show layer won't see this event anymore.

As you want to get informed about detailed structural changes of the data base, I would add the listener to the DataLayer, because there are no transformations involved.
