11371,"Logging: Advanced event log backend, Blank replaceable parameters",Eusebio Rufian-Zilbermann <eusebio@…>,Andrey Semashev,"Overview: I'm trying to use Boost Logging for sending events to the Windows event log. In the event log the replaceable parameters are showing up as empty strings, E.g., for a message of ""Operation finished successfully in %1 seconds."" the event log will simply show ""Operation finished successfully in seconds."" and the value for %1 is lost (instead of replaced into the string).

Code: I reproduced this problem on the example provided in the boost distribution itself (libs\log\example\event_log), after commenting out the custom event mapping section, to work around the issue described in ticket 9292, https://svn.boost.org/trac/boost/ticket/9292

=======Event mapping section to be commented out======
    sinks::event_log::custom_event_type_mapping< severity_level > type_mapping(""Severity"");
    type_mapping[normal] = sinks::event_log::make_event_type(MY_SEVERITY_INFO);
    type_mapping[warning] = sinks::event_log::make_event_type(MY_SEVERITY_WARNING);
    type_mapping[error] = sinks::event_log::make_event_type(MY_SEVERITY_ERROR);
    backend->set_event_type_mapper(type_mapping);
=======End of event mapping section to be commented out======
