Hi Hironmay-

I tried the following:

var nodeConf:NodeConfiguration = chatModel.getNodeConfiguration("HISTORY_NODE_EVERYONE");

nodeConf.persistItems =

false ;

chatModel.setNodeConfiguration(

"HISTORY_NODE_EVERYONE", nodeConf);

and got this error :

TypeError: Error #1009: Cannot access a property or method of a null object reference.

at com.adobe.rtc.pods.simpleChatClasses::SimpleChatModel/getNodeConfiguration()[....SimpleChatModel.as:388]

i also tried unchecking persistItems for the history nodes in Node Details via the AFCS Dev Console. that seems to make messages non persistent but only the first message sent shows up. every message after that never shows up in my chat window.

thanks.
