Programmatically set log level in log4j2

Hi all,
I am currently using the following code to dynamically update log level 
at runtime, after init:

         LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
         LoggerConfig logger = SyncopeConstants.ROOT_LOGGER.equals(name)
                 ? 
ctx.getConfiguration().getLoggerConfig(LogManager.ROOT_LOGGER_NAME)
                 : ctx.getConfiguration().getLoggerConfig(name);
         logger.setLevel(level);
         ctx.updateLoggers();

AFAICT, I can see that the level is actually updated after 
"ctx.updateLoggers()" using the following code (forgive the 
'System.out.println', it's just temporary...):

         for (LoggerConfig logger : 
ctx.getConfiguration().getLoggers().values()) {
             final String loggerName = 
LogManager.ROOT_LOGGER_NAME.equals(logger.getName())
                     ? SyncopeConstants.ROOT_LOGGER : logger.getName();

             System.out.println("Found logger '" + loggerName + "' with 
level " + logger.getLevel());
         }

Unfortunately, the level change is not effective: setting some logger's 
level to DEBUG does not change anything in the log files.
Am I doing something wrong? Thanks for your support.

Regards.

Hi all,
it seems that yesterday I was making some stupid mistake: I confirm 
everything works as expected.

Regards.
