May I add something to this undocumented error 2072 issue?
(VFP 8 on Windows XP Pro, SP1)
Today I received the same error but in a somewhat different circumstance.

It occurred on the following REPLACE line (in a procedure called from a grid's textbox's VALID event):

if ( ! ( alltrim( provFacilDtlCurs.ProvRefKey ) == alltrim( .ProvLkUpKey ) ) )
  replace provFacilDtlCurs.ProvRefKey with .ProvLkUpKey ;
       ,  provFacilDtlCurs.ProvFacil  with .ProvFacil
 
  ... (more code)
endif

The object reference and its two properties do exist just fine.

The cursor's cursorgetprop( "buffering" ) value is 5 – Optimistic table buffering. This cursor is not indexed. There is no save of any kind in progress.

Because the cursor is obviously not shared and in pure development phase here there are absolutely no other users I am not yet sure what to make of this undocumented error? Anyone's thoughts would be appreciated.

Thanks!
