I'm seeing these messages in my trace output; "Wt: decodeSignal():
signal '???' not exposed"

What does this mean?

I get that whenever I click on a button on a page when the "Loading..." icon in the red right is visible, which is about 90% of the time when you're running Wt in the debugger.

I'm looking into this now, and intend to implement more server pushes than pulls: http://redmine.emweb.be/boards/1/topics/11228

Hey Mark,

These could be innocent, but aren't always. This error is given if an event
is relayed from the browser to the server while the server hasn't exposed
this event. Unfortunately, because events are posted in batch to the server
(and queued up until you get a response), the typical case where the error
is innocent is when the widget is being deleted by a first event, that
would receive the subsequent events. In 3.3.5, we added an additional check
that mitigates this specific case. But you may still see spurious errors.

When you do have a real misbehavior, these errors may be a hint (especially
to us) that something real is wrong related to widgets and events.
