I am using Drupal 7.19, Views 3, CiviCRM 4.2 and Full Calendar 2.0.
I am getting the error message: Display "Page" requires at least one date field.
even though I have selected CiviCRM event start date.
I can use start date in other views not requiring Full Calendar.
I have tried deleting the View and creating a new on but that hasn't helped.
