What will happen when a Button’s OnClick action triggers without an Event handler for MyEvent defined?

When a Button’s OnClick action triggers an event and there is no corresponding event handler defined for that event, the expected behavior is that the application will encounter a runtime error. This occurs because the action is attempting to execute an event that the system does not recognize or cannot process due to the absence of the necessary event handling logic.

Event handlers are designed to capture specific events and define what should happen when those events occur. In this scenario, the button triggers the action to raise an event, but without an event handler for "MyEvent", the framework cannot find any instructions on how to handle this scenario. This results in the runtime raising an error, indicating that there is no appropriate handler for this particular event.

In contrast, the other options suggest outcomes that do not accurately reflect the behavior of the OutSystems platform in this case. For instance, while the application might log errors in other situations, simply not having an event handler directly leads to a runtime failure rather than just logging an error. Similarly, stating that the trigger Event statement will have no effect ignores the fact that calling the event without a handler has specific consequences in terms of error management. The idea that the button action could execute successfully is also inaccurate because the absence of an event handler indicates that
