Hi all,
after upgrading to Wicket 7.6.0 [1], this code [2] is causing the
following error in the logs:
10:02:16.300 ERROR org.apache.wicket.protocol.ws.javax.WicketEndpoint -

The error is repeated for each page, with connection id incremented.
This used to work fine with Wicket 7.4.0; with Wicket 7.5.0 we had to
introduce this backport [3] which seems anyway not affecting the problem
above.
Could you please shade some light? Thanks!
Regards.
