Which source is automatically selected when using the form builder?

The form builder in Pega is designed to streamline the process of creating user interfaces by automatically selecting the most suitable data source for the context in which you are working. The reason a page list property is automatically selected is that it provides a structure to hold multiple records and allows forms to dynamically display this data in a way that can be easily manipulated by end users.

Page list properties are well-suited for scenarios where a collection of items needs to be displayed or manipulated, making them ideal for forms that need to capture or show multiple inputs. Since the form builder often aims to facilitate user interaction with lists of data, selecting a page list property helps ensure that the form is effectively aligned with user experience goals and provides flexibility in displaying multiple records.

In contrast, data pages, report definitions, and clipboard pages serve different functions within Pega. Data pages are used to retrieve data for specific use cases but are not necessarily the first choice for direct form creation. Report definitions are designed to generate sets of reports and may not be structured optimally for form input. Clipboard pages serve as a representation of the application's data in memory but do not directly serve as a data source for forms. Thus, a page list property aligns best with the intended use of the form builder.
