Listeners for DataSource Changes?

I’m working on a Vaadin7 Extension that extends Table instances. The extension needs to be notified of changes to the table columns. I have attached listeners for most of the relevant events I need, but have hit a brick wall on one particular event: calls to table.setContainerDataSource() leave my extension completely blind to the change.

Am I missing a listener/event type, or is there currently no way to monitor this change?

Table is a Container and implements (indirectly, via AbstractSelect) ItemSetChangeNotifier. Thus, I would find it logical to assume that they would fire either such an event or a more specific event on container data source change.

If this is not the case, please
create a ticket

That event doesn’t fire for me with Vaadin 7.1, so I’ll file a ticket.
