Debugging Events
You can debug events to help you find and correct errors. Debugging events is similar to debugging other C/AL code in an application, where the basic concept is the breakpoint. To debug an event, you can add multiple breakpoints on event-related lines of code that cover each phase of the event, as described in the following list:
| Event Phase | Breakpoint | Description |
|---|---|---|
On publishing an event |
Add a breakpoint in the event publisher function that declares an event. Although an event publisher function does not contain any code, except comments, you can add a breakpoint on a non-code line. For more information about publishing and event, see Publishing Events. |
This enables you to step into the event handler code in event subscriber functions that subscribe to the event, without executing code that raises an event. |
On raising an event |
Add a breakpoint on the line of code that calls the event publisher function which raises the event. |
This enables you to step into event handler code in event subscriber functions from where the events are raised. For more information about raiding and event, see Raising Events. |
On subscribing to an event |
Add breakpoints on lines of code in the event subscriber function that subscribes to a raised event. |
This enables you to step through code that handles an event. For more information about publishing and event, see Subscribing to Events. |
