REST API backed custom picker field in an editable user grid

Question

Scenario: User wants to bulk edit rows of data which have been stored in MariaDB. User is presented with data (ranging upto 150 rows) in an editable grid. The first column in the editable grid is a picker field whose suggestFunction calls an external REST API. When the user loads the page (clicks "edit" record), will the REST API be invoked per row of the editable grid?

It depends a bit on how you return the data from the suggest function. The field "identifiers" is an ANY type. Means, that you can store a list of maps in there that can then include the actual identifier plus the display value. Check out my blog post where I describe how to allow adding new items from a custom picker.

Yes, it will be invoked for each custom picker field. Why don't you save the response in a local variable outside and pass it to suggestion function?
