Query data is unavailable for binding and to be populated for Dynamic Attributes when I format their Repeat expression from Data View, for example, in my case data_usermanagement.data.sort(sort_user.value).

Hello Firdaus,
It is not really clear what data exactly is not available for which element?
Can you please explain step by step what exactly are you doing, what exactly do you have on your page and what/where is missing?

As you can see here, I want to bind something from Repeat:repeatuser but it keeps loading, and its source, Data View:datausermanagement.data also has no further query, which actually existed before I apply formatting to its Data Source as shown here.

The page works fine and no error, the only problem is with the Data Binding Pickup interface. Perhaps it is unable to populate data with formatting. I hope this can be solved.

Hi Firdaus, thanks for clarifying this. We will check the issue.
