What prerequisite is required for executing a Screen Action with Ajax Submit?

When executing a Screen Action with Ajax Submit, one important prerequisite is that the widget must have a Name. This requirement enables the framework to identify and manage the state and behavior of the widget during the Ajax submit process.

Naming the widget is crucial because it allows the system to associate the action taken with the specific widget, facilitating the correct handling of data when the Ajax request is made. If the widget lacks a name, the framework will not be able to process the Ajax Submit properly, as it would not know which widget's event is being invoked.

The other prerequisites listed do not directly impact the execution of the Screen Action with Ajax Submit. For instance, a screen does not necessarily need to be linked to a database to perform actions through Ajax. Similarly, user login status and the action being public do not specifically relate to the functionality required for Ajax submissions; rather, they pertain to broader application security and access management within the OutSystems environment.
