Hi Yan,
Lluis's (and my) point is that if you're trying to do this during the
software development process (as opposed to needing to log these details in
a production system), then the debugger with breakpoints is definitely the
right tool (as opposed to running with log statements).
If you're not familiar with how to do this, hop on the OpenMRS IRC channel
( https://wiki.openmrs.org/x/EQAP ) and see if someone can help you with it.

Just curious, why do you use logging for debugging purposes ? I mean,<br>
logging is good in production where you can't use an IDE to debug, but<br>
in development it's weird.<br>
