Wt

This is a warning message: the application is getting an event which is currently not accessible through the UI. This is part of the security system of Wt. It is possible that you get this occasionally if the state of the browser goes (temporarily) out of sync with the state of the server. A simple example: pushing a button twice rapidly in succession, but a slot associated with the event deletes the button. Then the second event will be logged as not exposed.

You should not see this message consistently and certainly not associated with misbehavior. Should that be the case, I would like to know more of which events are being generated, and how you are populating the treeview ?

We are not hearing anymore from the original submitter
