Checking he values of a Pagelist for a constellation application
I know this is more of a general question but thought I would ask to see if someone would provide me with a solution. I have an embed Pagelist displayed In a table and within the flow action I will have a post event to check the values for duplicate values - I know I need to use a data transform but wanted to know the best way of checking for the duplicates on say a field call name in the Pagelist.
Thanks,

Hi Ian, backend processing is the same for Constellation and for Traditional Architecture.
There are couple of options: - you can manually loop over the list and with function IsInPageList do filtering manually - or you one of the ootb function. Please check CheckDuplicatesInPageList or removeDuplicatesFromList

@IainTollemacheInfinity '25 will have this capability, you can run the Action (Flow Action) directly from the table. That action can have the post processing and validation you are after, direct in the modal.
In '24, you'd have to use Form Refresh settings or the primary User Action (Flow Action) to check for duplicates inside that embedded data.
