I have a form that has a people picker and allows for multiple entries, it resolves the users just fine but when it comes time to save or update the item it fails saying it cant find the user. 

This smartform is using a smartobject to update a list item in SharePoint 2010 and it should be saving these user names to a people lookup field that allows multiple users.

How can i achieve this? Has anyone been able to do this?

thanks in advance.
