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.
