Tracing an OpenLaszlo build
A stack trace shows which methods and handlers are called while the application is running.
The debug console shows all logged messages. Use this information to view the associated stack trace.
To enable tracing, see Building OpenLaszlo applications.
Clicking any warning, error, or debug messages, logged in
the debug console, displays extra information including a backtrace.
The backtrace shows the method calls that lead to the logged message.
In this example, a debug message is printed from Service.lzx line
1165:

When you click the backtrace link, the methods that led to the debug message are printed.
When you click the backtrace link, the methods that led to the debug message are printed.
The backtrace option is also available not only for debugging but also for error and warning messages. Click an error message to see the backtrace of what caused the error.
When adding debug messages to your code, use the Debug.debug() method to print messages instead of the Debug.write() method. This method ensures that your messages contain a backtrace. Calls to Debug.debug() can appear inside handlers, methods, and attribute setter methods.
