Which statement is false regarding screen aggregates?

The statement that all Aggregates have the Fetch property set to On Demand by default is incorrect. In OutSystems, Screen Aggregates typically default to automatically fetching data when the screen is loaded, rather than being set to "On Demand." This means that unless explicitly configured to fetch data on demand, a screen aggregate will execute and retrieve its data during the rendering of the screen.

When a Screen Aggregate is created, it is often set to fetch the required data immediately without needing an explicit trigger by the user, which aligns with the typical workflow in OutSystems applications. This behavior is essential for ensuring that users have the data available as soon as they access a screen.

In contrast to the other statements, which describe standard functionalities such as rendering events or fetching triggers, this particular statement does not reflect the usual behavior of Aggregates in OutSystems. Therefore, the identification of this statement as false is based on the default characteristics of Aggregates in the OutSystems development environment.
