Symptoms

Picker Control named incorrectly
 

Diagnoses

When creating an application off a SharePoint list that has a Person or Group Column, the picker control that gets auto generated for that Person or Group field gets named ' Column Name] Text Box' instead of ' Column Name] Picker'.
 

Resolution

Picker control gets named incorrectly due to a bug which has been logged. To workaround it, simply rename the control in the properties menu.
