Thank you for the multiselect in Autocomplete - I can see the data in body.
However, how do we access the eventdata in UDstepper? Just need to ensure when user press back button, the data previously entered data is selected.
So what I figured, the $eventdata.context.position is there. But when I put it in the value, press the back button, the value is returned in one string - if a user select one value its fine. If a user selected multiple value, everything will be in one string. This is probably the autocomplete script parameter which only accept [string] value instead of array.
Updated the [string]$Value to [string]$Value fixed the problem.
