Hi @Kamil Janeczek,

I have some basic questions.

In a constellation, is it always recommended to create a new data model either in the implementation layer or organizational layer (e.g., Contact), or can we reuse an existing data model (e.g., PegaDATA-Contact) through inheritance? I haven’t found any documentation references on this. What is the recommended approach for a greenfield application?
Also, should we build a new greenfield application on top of the Pega Common Data Model application, or as a standalone? What is suggested?

Thank you.

How to Add Read-Only Text to the UI or View in Constellation Without a Data Model

In traditional UI, we add a paragraph to the section. Similarly How can we achieve this in Constellation without using a data model?

@Kamil Janeczek hi Kamil, how to configure 'Search and Select" feature in Landing Page? Use case is to build custom search capability to query data from external system or simplified view.

@Kamil Janeczek Hi Kamil - these are great standalone resources. The excellent Constellation Adoption mission (which I know you were a fundamental contributor to) is a more structured way to learn Constellation. It would be good for this audience to understand whether these articles are in addition to, fully covered or partly covered by the mission.

I’ll take another look at the SweetLife sample application and see if I can map these 101 articles back to specific parts of the learning journey provided by the mission.

@Kamil Janeczek I would like to clarify one issue I am getting on one of our Constellation application. We have an insight on one of our data type and it’s showing all the values correctly. However, while applying filter on one of our fields(Type-Text), it’s showing error. During inspection, I found the payload which shows that it has error but I am not able to find what’s wrong with that filter field. I have tried applying filter on some other text fields available on that Insight, all are working fine. I have attached the error details and also JSON Payload for the query.

@Kamil Janeczek

I have a requirement within the Pega Constellation architecture to display Customer Product Holdings in a hierarchical structure. Please refer to the attached image for a visual representation of the desired output.

Pega currently provides a built-in Case Hierarchy widget. Could you advise on the feasibility of leveraging this existing widget to fulfill my specific requirement?

Alternatively, I would appreciate suggestions for an official, out-of-the-box Pega approach to achieving this display without requiring custom implementation.

Hi @Kamil Janeczek,

We are facing an issue with Multi select / ComboBox fields in Pega Constellation Ul.
When a user submits a case with a Multi-select, the selected values display correctly on the entry screen. However, on the Review screen, the values are rendered as hyperlinks instead of plain text.
Is there any configuration or recommended approach to disable the hyperlink behavior for Multi select values and display them as non-clickable text?

@AK___thanks for questions I see them already answered here: Constellation- Ask your Questions! - General - Pega Forums

@A___K____ Hi Arunkumar,

In Constellation I see Form views allow to override case instructions, likewise we used paragraph rules in UI-Kit to add additional information to a collect information step.

Field groups also allow this, so you might add your text to either of those. So, in a nutshell you can combine Form views (like to add top instructions) and then field groups to add more focused instructions.

Hope this helps.

Regards,

Hi @Kamil Janeczek , Greetings. Hope you are well! I have a List being displayed with a single select, however i see the radio button selection is greyed out, i even tried with latest Search and Select but still the button is greyed out. I am on Pega 24.1.1. Please see below screenshots for reference.

Any suggestions?

Regards,
Bharat

@VenkatVVSearch and select pattern is available only for Data Reference field (so inside Case). For landing pages you can use promoted filters that are available on:

List Views
Insights

@Kamil Janeczek
I would like to ask one question regarding Converting Sales automation to constellation.
Can you please guide me on this and one important question I have is, for sales automation migration from UI kit to Constellation, do we need to build the application from scratch in constellation like how we are doing for Smart Investigation or we just convert UI kit sales automation through pega modernization assistant.

Please guide me on this. Thank you.

KamilJaneczek · August 11, 2025, 4:57am

@RumelaBasuhi, appologies for late reply. Could you please create a new conversation for this issue? To have a chance that other experts see your question.

@JagathP3

hi,
when you are working with prescribed design system you have set of features and configurations at your disposal. Constellation is exactly like that, but more to that it allows for extension. So if needed you can build your solution to look like the one presented on a screen.

If you would like to take advantage of what is ootb in Platform or as extension in Constellation UI Gallery: GitHub - pegasystems/constellation-ui-gallery: This open-source repository provides a collection of ready-to-use and customizable Constellation DX components. Use this resource to gain inspiration, best practices, and a solid foundation for implementing custom components. · GitHub, then better starting point is description of business needs rather that mockup or print screen.

Having the business needs (not the ui requirements) we can think what ootb pieces we can use to assemble the solution.

KamilJaneczek · March 3, 2025, 7:29am

@KOMARINA Hi, which button is greyed out, the radio buttons? It is not evident from the screenshot. Can you attach configuration of this field?

KamilJaneczek · March 3, 2025, 8:39am

@KOMARINAthanks, I would need to play with it. Never seen it. Any specific custom with configuration of data page?

KamilJaneczek · May 20, 2025, 2:04pm

@Niall (ComponentMaker)Thanks Niall. Those materials are meant to extend what we covered in Constellation Adoption mission. This is in response to many voice that SAs/LSAs need more practical and hands on experience.

I would advise everyone to go through Constellation Adoption mission and then search for additional guidance in Constellation 101 series.
