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 :~

Thanks for any pointer.
