We are in the process of upgrading our apps from WO5.3 to 5.4 and have come
across another strange error:

.webobjects.eoaccess.EOGeneralAdaptorException: Unsupported feature

 at java.lang.Thread.run(Thread.java:613)
-  Additional info:
-  EOAdaptorOperationsKey = class com.webobjects.foundation.NSMutableArray
-  EOFailedDatabaseOperationKey = class
com.webobjects.eoaccess.EODatabaseOperation
-  EODatabaseOperationsKey = class com.webobjects.foundation.NSArray
-  EODatabaseContextKey = class
com.webobjects.foundation.NSMutableDictionary
-  EOFailedAdaptorOperationKey = class
com.webobjects.eoaccess.EOAdaptorOperation


I am not sure what this error is indicating. It looks like something in 5.4
does not like something 5.3 never complained about. The only thing I can
think is that we registered a EODatabaseContext delegate at app start up to
generate our own primary keys. The error appears to be isolated to just a
few places. There are other places in our app where we can save our changes
just fine (and generate correct primary keys as well).

Any thoughts or ideas are appreciated. Thanks in advance
