There are two types of log files available in Bonita Studio: one for the process, and another for the Bonita Execution Engine. They are both accessible are via the Menu Bar: Help > Show log and Help > Show engine log.
When you encounter a problem during development, you can refer to these logs for the process run history.
You can always post a description of the problem and a copy of your log file on the Bonita Community Forum at www.bonitasoft.org/forum/.
