Debugging Appeon Web Applications

Sometimes a deployed application may not behave well although the original application does. In these situations, you can examine the execution results of the JavaScript code in the deployed application using Appeon Debugger.

The usage of Appeon Debugger is similar to that of PowerBuilder Debugger. You set breakpoints or watch variables in the PowerBuilder source code, same as in PowerBuilder Debugger. The main difference is that Appeon Debugger runs the generated JavaScript code but not the PowerBuilder source code, and shows the execution results of the JavaScript code.

This chapter assumes that you are familiar with the functions of PowerBuilder Debugger; therefore it does not provide descriptions of common debugging features, but focuses on introducing the specialties of Appeon Debugger. For common debugging features, refer to the Debugging an application section in the PowerBuilder User's Guide.


  1. Appeon Debugger can work on both 32-bit and 64-bit machines.

  2. Appeon Debugger only works with 32-bit IE 8.0 or earlier versions (does not work with 64-bit Internet Explorers), and will support to work with 32-bit IE 9/10/11 in the next version. However, you can run (not debug) the Appeon Web application in IE 11 or earlier versions (both 32-bit and 64-bit).

  3. Appeon Mobile provides no debug tool, but you can still take advantage of Appeon Debugger to debug the business logic of the mobile application.
