I spending hours on this matters but still could not figure out what has been gone wrong. I have a repeatition that shows displayedObjects of a display group. Checked wod, woo and coding and things looked normal.
Anyone to help why WODisplayGroup complains about displayedObjects variable not found? The following is the short error message :~
[2010-6-29 18:11:30 SGT] <WorkerThread0> <com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException message '<com.webobjects.appserver.WODisplayGroup 0x1694eca> takeValueForKey(): attempt to assign value to unknown key: 'displayedObjects'.
