My use case is that the data takes around 10 seconds to load to the the Data page Page List (Connect Rest) and i am using the D page in my Embedded data and displaying as Repeating View. For example ContactHistoryInfo is the Data Page List used in the embedded data. [Screenshot 2026-05-22 at 10.26.18 AM] Now in Constellation, the UI initially loads without the data, and currently I have to manually refresh the entire screen to see the updated data once it becomes available. Is there a way to make the UI update dynamically so that the data automatically appears after the 10-second load time without requiring a full screen refresh?

How did you configure an embedded data field with a Data Page?

I just created a property of embedded data type and inside that mentioned the data object and chose list of records which uses the Data page list of that data object [Screenshot 2026-05-25 at 9.54.28 PM]

Are you copying the data from the data page into this embedded data in the pre processing data transform?

Yes that is how i am implementing this

Instead of using a pre-processing Data Transform on the assignment step, try moving that data-copying logic into a Data Transform configured on the flow connector line right before your step. Shifting the logic to the connector line ensures the asynchronous REST integration completes and populates the embedded data before the UI view attempts to render. This will resolve the issue and ensure the data is fully present and visible as soon as the user lands on the assignment screen.

Actually the thing is i want to implement an action then show the data which is taking 10 seconds but is visible only when we refresh so as in constellation there is no action set what i tried i like creating a async activity used Load Data Page and then Connect step and after that used a property “FLAG” and used property set to change the value of “FLAG” now in the form refresh setting i thought of using this “FLAG” and in the DT of this i would map values from the Data page to my case properties now the thing is in Async Activity i cannot use Property Set so i dont know how to pull this off.

It seems the connector is taking about 10 secs to fetch the data from external system. If you’re looking for the User interface to be refreshed automatically once after connector, then leverage this pyPublishMessageForCaseRefresh activity Pegasystems Documentation

What action do you want to implement? Do you need to select a check box or something like that?

so basically i want to implement a button or some action which on clicking will show the data coming from a Data page but in constellation we don’t have the feature of buttons

Form Refresh settings Data transform gets triggered only whenever there is UI changes to the fields that you configured. Also, please check this article - How to notify users to refresh an outdated List View in Constellation UI
