I have cross-checked with other components that contain display groups. But no clue. The moment I added this display group into the component, the error will happen at appendToResponse.

Thanks,

ps. It is late night and I may not be able to response with more info later...

Hi Cheong,

the error says that you are trying to set a value for displayedObjects though this is not a settable value. Please post your bindings/html where you are using the display group so we can see what is exactly happening.

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'.

Thanks for any pointer.
