'System.Data.DataRowView' Does Not Contain A Property With The Name 'xy'

my environment: VS2005, SQLExpress with SP1, WXP with SPs,

the error msg I get is: 'System.Data.DataRowView' does not contain a property with the name 'change'.

The base for all this is the 'MS Club Site' sample code downloaded from ASP.NET!  

After adding a new data field "change" to my DB I changed the StoredProcedure "PagedUpcommingEventList" (statement 31) and in the 'Repeater' I added statement 32 to reflect this change (see code below). When calling 'Configure Data Source' on the SQLDataSource I can read the DB (using the StoredProcedure) but I never see the new field 'change'!
I certainly checked for additional StoredProcedures with the same name: "PagedUpcommingEventList" --- I definitely have only one in my project.
PS: In another .aspx file using a SQLDataSource with a DataGrid; the field is showing up correctly!

I spent days in the area of 'caching' without any success; thought the StoredProcedure is always called from the 'cache'! .... Thank you for your time .... any idea is appreciated!
