In Guidewire PCF (Page Configuration Framework) development, the selection of the correct widget is driven by the underlying data relationship. In this scenario, a "Reference" is a separate entity, and an Account (or Contact) is likely to have multiple instances of these references (a one-to-many relationship). According to Guidewire best practices, when you need to display a collection of objects—especially when that collection can vary in size or requires the user to see multiple entries at once—theList View (LV)is the standard and most efficient UI component.

AList Viewprovides a tabular format that allows users to view, sort, and sometimes edit multiple records simultaneously. By creating a ReferenceLV.pcf and embedding it into the ContactSummary.pcf (typically via a PanelRef), the developer provides a clean, scalable interface. This approach is superior to aDetail View (DV)because a DV is designed for a single record's specific fields; attempting to hard-code "three references" into a DV (Option A) is fragile and non-scalable if the business requirement later changes to four or five references.

Furthermore, embedding the List View directly on the Summary page ensures that the information is immediately visible to the user ("at a glance"), which aligns with the purpose of a "Summary" page. Using aPopup(Option B) adds unnecessary clicks to the user workflow, and anInput Set(Option D) is generally intended for grouping related input fields within a Detail View rather than managing a collection of entity instances. By utilizing the List View, the developer follows the architectural pattern of "Master-Detail" or "List-Detail" commonly found throughout the InsuranceSuite applications, ensuring the UI remains consistent with the rest of the Guidewire platform.
