Detach event does not update connection list

[abombelli]

When using the event listener detach, and then calling getConnections(), it doe not reflect the new set of connections.

instance.bind("connection:detach", function (info) {
console.log(instance.getConnections());
});

The detached connection is still present in getConnections().

When I add instance.deleteConnection(info.connection); , then instance.getConnections() reflects the correct connections, but it triggers the following error:
[Log] jsPlumb function failed : TypeError: null is not an object (evaluating 't.endpoints[0]') (tool.8358ff.js, line 1)
Any idea why?
