For debugging und logging output the class Message is used as well:

• The method Message::trace creates an output in the view, if the debug entry in the configuration is set to 1 - otherwise the output is suppressed (see configuration section cms).
• The method Message::log creates an output in the application's logfile (see configuration section cms)

To output complete objects in the view the method Message::dump is used. The following method call writes the same dump into the logfile.
