Recently a calendar was created in a Site Collection with a personal content type and a personal column. When I tried to save after adding a new event or modifying the event, I have the famous error an expected error was occurred.

My log file in the severity is Unexpected:

System.NullReferenceException : Object reference not set to an instance of an object � Microsoft.SharePoint.Applications.GroupBoard.WebControls.OverbookField.get_IsRecurrence() � Microsoft.SharePoint.Applications.GroupBoard.WebControls.OverbookField.BuildSPItem() � Microsoft.SharePoint.Applications.GroupBoard.WebControls.OverbookField.IsOverbook() � Microsoft.SharePoint.Applications.GroupBoard.WebControls.OverbookField.Validate() � System.Web.UI.Page.Validate() � System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) � System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) � System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) Severity High:
