Debugging Web Dynpro Applications Using the Context Menu

Use

When debugging Web Dynpro ABAP applications it is important to go as quickly as possible directly to the place in the Web Dynpro coding where a problem is likely to occur. To enable this, debugging entries have been added to the system context menu. In addition to the entries Show Quick Help and More Field Help, the following entries are now available:

  • Activate Debugger

    • In the Event Handler of the UI Element

    • WDDOBEFOREACTION

    • WDDOAFTERACTION

  • Deactivate Debugger

    • In the Event Handler of the UI Element

    • WDDOBEFOREACTION

    • WDDOAFTERACTION

    • Delete All HTTP Breakpoints

Activating and Deactivating Debugging

  1. Set an external breakpoint somewhere in the coding where your work will not be affected by it.

    An external breakpoint is necessary so that the application server opens the debugger in the correct GUI. If you omit this step you will be reminded in the Web Dynpro context menu (entry Start of the navigation pathActivate Debugger Next navigation step Set an External BreakpointEnd of the navigation path).

  2. Start your Web Dynpro application with URL parameter /H=X.

  3. Open the context menu of a UI element that triggers an action, and select the required entry for the debugger.

  4. Debug your application.

  5. When you have finished debugging, you can delete your breakpoints using the entries in the context menu mentioned above.
