[logback-user] Invalid URL reference in logback error code

Hello logback users,

When trying out perf4j's recently added support for logback I followed
example from perf4j logback package javadoc which can be found here:

That example at the moment has a bug, perf4jFileAppender is referenced
from a logger, but the appender is listed in configuration file after
logger. Logback's AppenderRefAction reports this as an error with
following code

    Appender appender = (Appender) appenderBag.get(appenderName);

    if (appender == null) {
      String msg = "Could not find an appender named [" + appenderName
          + "]. Did you define it below in the config file?";
      inError = true;
      addError("See " + CoreConstants.CODES_URL
          + "#appender_order for more details.");

Url this produces in logback-classic 0.9.30 is
When accessed, error codes page opens, but on it there is no
explanation for this error and in the page source there is no element
with appender_order id.
Couldn't find in the history of the codes.html page (
) one revision that ever had this.

Am I missing something or is this a bug in logback site?
