Displaying Just Nicknames

I just set up my first version of my own Flash Client and it basically runs off the code supplied with the XIFF kit. What I’m looking for is a way to populate that datagrid in the example with just the user’s nickname. I’ve tried to trace out all the parts of the dataProvider “chatRoom” - I’ve tried to build a custom object that just takes on the nickname attribute but my understanding of how it works is a bit limited. any help would be appreciated.

var chatRoom = new Room( connection );

chatRoster.dataProvider = chatRoom;

chatRoster.columnNames = (LEFTBRACKET)“nickname”(RIGHTBRACKET);

This answer has been posted several times but comes up as BLANK!!!

This is the lame solution that its purely graphical. Not sure how to filter the actual data under dataProvider.
