User Interface Development & Navigation Flashcards

Which Pega configuration enables a dropdown field to automatically populate its list of options from a data page?

Answer: Data page source set on the control's options list

Setting the control's Options source to a Data Page causes Pega to invoke the specified D_ data page at runtime and use its results to populate the dropdown.

In Pega, what is the difference between a 'stage' and a 'step' in a case lifecycle?

Answer: Stages contain steps; steps represent individual user or automated tasks within a stage

Stages are high-level phases of a case (e.g., Intake, Review, Resolve), while steps are the individual tasks within each stage that users or automations complete.

What is the recommended Pega approach to display an error message inline on a specific field when a business validation fails?

Answer: Return a message from an Edit Validate rule associated with the property

Edit Validate rules return parameterized error messages that Pega displays inline next to the field when validation fails, following the low-code best practice.

In Pega App Studio, which setting controls the channels (web, mobile, email) through which a case type is accessible to users?

Answer: Channel interfaces configuration

Channel interfaces in App Studio define how and through which delivery channels (web portal, mobile app, email) a case type's UI is surfaced to users.

Which Pega control type should you use when you need the user to select exactly one option from a small set of mutually exclusive choices displayed all at once?

Answer: Radio button group

Radio button groups present all options simultaneously and enforce single selection, making them ideal for small sets of mutually exclusive choices.

What does the Pega 'Refresh when' condition on a section or control do?

Answer: Re-renders the section or control on the client when the specified condition becomes true

'Refresh when' causes Pega to perform a partial page update (via AJAX) on the specified UI element when a data change triggers the condition, without a full page reload.

In Pega, what is the purpose of a 'Modal dialog' in the user interface?

Answer: To display a secondary form or confirmation in an overlay without navigating away from the current screen

A Modal dialog opens a focused overlay form on top of the current screen, typically for confirmations, quick data entry, or detail views, while keeping the background context visible.
