   We just started trying to use these and have them working. Is there a way to add an extra entry to the select dialog that is not in the DB table? For example, we support values of 0 or "" depending on data type which would be the initial value. After selecting a record from the SME Lookup in order to reset that back to 0 or "" the user would have to clicking into the field and clear the value. We would prefer to set READ-ONLY = TRUE for the control and force the user to click the editor button and choose a record with 0 and a Description of "None".
   
   Maybe  in "AfterInitializeBusinessEntityAdapter" I can add the extra record? Is there a better place?

   I typically solve those requirements by adding a second editor-button with a "clear" function.
   
   Injecting an empty record is something I have never tried.
   
   I would expect that the AfterInitializeBusinessEntityAdapter event is too early. As the RetrieveData is called after that. However in that event you are receiving the reference to the actual SmartBusinessEntityAdapter. I would actually try to solve this on the backend - use the AfterInitializeBusinessEntityAdapter event to set the Business Entity Adapter's "CustomContext" property to a value like "IncludeFlagValue". Then in the Business Entities's override of the FetchData() method (the one with the IFetchDataRequest parameter), do the 
   
   SUPER:FetchData (poFetchDataRequest) .
   
   and then 
   
   IF poFetchDataRequest:CustomContext = "IncludeFlagValue" THEN DO:
     /* create the extra record */
   END.
   
   There may be complications with batching that require fine tuning though. Is it o.k. to set the BatchSize to 0 ?
   
   For small sets of data, I'd go with the SmartComboEditor instead. This supports a "flag" value which is typically either the "none" or "all" kind of entry.

   batch-size of 0 would be fine.
   
   I will look at the smartcombo.
   
   thanks.

   Hi Mike,
   
   I ended up going with the SmartComboEditor as you suggested. The FlagText and FlagValue are extremely useful.
   
   For larger sets of data we will use the SmartBusinessEntityLookup and add a "RESET" button.
   
   Thanks!!

   Please use the SmartComboEditor - not the SmartCombo.
