Thanks. That control worked. Additionally, I created a simple workflow to take the AccountID and populate it's value to a standard person or group column, which will allow for the standard SharePoint functions (view user profile, email).
I notice that this works well if I only pick one person. Is there a way to use the Contact Selector for multiple selections? The control allows you to select multiple values and merge the data into the SharePoint library. I changed my Assigned To column to allow for multiple selections, but my workflow errors when I run it. I'm assuming that the data needs to get parsed before the value can get set to the Assigned To column. Is this possible?
