Are you sure you have no external file references? This sounds exactly like that issue. If you select Manage | External Data Sources, can you confirm that nothing is listed here? It's possible for a file to have an external data source reference to itself so check for any entries in this section.
If that's not the case, check the details of how this value list is defined. Certain special functions may specifically refer to the current file by its name and they will then break if you rename the file. If your value list draws its values from a calculation field that uses one of them, you may end up with an empty value list when you rename your file.
ValueListItems is one such function unless you've specifically used it with this format: ValueListItems ( get ( FileName ) ; "valueListNameInQuotes" ).
I think that somewhere you used the ValueListItems ( ) function, hard-coding the FileName instead of using Get( FileName )
Edit: Phil, I didn't see your answer.
You guys are the best. Buried deep in a case statement there was indeed a hard coded ValueListItems. Thanks to your direction and the Database Design report it was a quick fix.
THANK YOU BOTH- michael
