InfoPath Dev

Hi Guys, I have a big problem with Infopath and the people picker. The problem is following: There is a button with the function to write four accounts to the people picker field. If I click the button the accounts will be added but they won't get resolved automatically. Do you know if there is any possibility to resolve the names automatically? The accounts have following format: DOMAIN\username1; DOMAIN\username2; DOMAIN\username3; DOMAIN\username4.

No, it's not going to automatically populate DisplayName. I recommend just calling GetUserProfile service and getting the names and then setting them in a custom repeating table. You can trigger variable number of lookups by adding default rows to your repeating table and adding a rule to the row that calls the GetUserProfile service to lookup the display name.
