I have couple of people/group picker controls on a form (not directly tie to a list). they work fine but shows accountname (for example, jsmith). I like to show "John Smith".
I dont want to call profileservice webservice and do the filtering thing to get the display name.
However, form design from a different list (with people/group columns in it and configured to show name or you can show id or what have you) then infopath form shows Name not id.
I hope I am making sense.
