RadDataForm - AutoCompleteInline - New values



I am currently adding a tokens-based AutocompleteInline field to my form based on:

From the text

This editor also uses a predefined list with values, but they are not the only acceptable values, but rather they are suggestions that are displayed when the user starts typing for the keyboard.

I derived that new values can be added, too. But it does not seem to work for me. If I have a value provider with existing values and add these the field works fine.

If I enter values not available in the provider nothing happens and I cannot “enter” them.

Is this known and expected, am I misinterpreting the text?

Or is there an event listener I can check up on during input that always returns the current typed?

Thanks a lot
