To be more precise,
I have a sharepoint list--> tower(Id, TowerName [Text datatype], Tower Lead A[people Picket datatype], Tower Bead B [Text datatype]).
I have a dropdown which is getting populated from the tower name from the sharepoint list.
When i select the Tower in the dropdown, the Tower Lead A and Tower Lead B is to be populated in the Infopath form.
This thing is working fine for Tower Lead A and Tower Lead B (i can see this because in the Preview it works fine) but when i do a publish, the same does not work for the population of the People Picker datafield. where in Tower Lead B is working.
I hope i am clear now with the problem. I have checked the data connections as well, but not able to find the issue. Please provide inputs.
