Which of the following behaviors does not apply to Forms?

The correct choice indicates that a Form does not have a Source property to hold the values submitted by the user. In OutSystems, Forms are indeed designed to gather user input and handle data, but the way they manage values is through specific input widgets contained within the Form rather than depending on a singular "Source" property. This mechanism allows forms to directly interact with the input fields, validating and processing data as users submit it.

When considering the other options, it's important to recognize that Forms do group input widgets effectively and facilitate the display and editing of data, which aligns with the functionality expected in web applications. Additionally, Forms can indeed encompass other widgets like Links and Buttons to enhance interactivity and provide necessary actions for users. Lastly, Forms are utilized for data validation, ensuring that the information entered aligns with set criteria before being processed further. In summary, the unique structure of Forms focuses on the aggregation of input fields rather than relying on a singular property for handling submitted values.
