Hi folks,
So Prompt API seems like the new thing introduced for 10.2 and it involves Javascript. Since Javascript is not supported by IBM, but the Prompt API examples provided by IBM do have Javascript, is Javascript used in Prompt API supposed by IBM?
That's a question best introduced to your IBM service contact.
Having said that, the functions offered by the prompt API should be supported, that is they should keep doing the same thing in future versions. Any additional logic based on the DOM might be subject to change in future versions.
