Would your fetch specification have the raw row flag turned on?

Hi WO Dev List,
We have moved several apps to Leopard/WO5.4 successfully (not D2W),
but we have one D2W application which produces the following
exception when a search of some data is triggered by clicking on a
Search button in the app. As D2W is 90+% WO doing its magic stuff, I
am not quite sure how to track this problem down. Can anyone advise
on why there might be a cast class exception of NSMutableArray
within eoaccess when DTW is running a query? This worked ok pre-WO5.4.
