RE: [flexcoders] LCDS : ReferenceError: Error #1056:

I think you may have a newer server running against an older version of 
fds.swc.   Make sure you are using the fds.swc which comes with that version of 
LCDS.

Hi People,

I am using the Data Management Service of Livecycle to keep track of
users logged in.
When I call the fill method the first time, everything works fine. I
get back an arraycollection which is shown in a datagrid.

But when I try to add a new user (by clicking on the button "login"), I
always get the following error :

ReferenceError: Error #1056: Cannot create property size on
mx.data.UpdateCollectionRange.

I don't find this error in Google and I am seeking on this problem for 2
days now... so, the flexcoders list is my last hope :)

Thanks a lot in advance !
Bart

You'll find the client side code below :

ds = new DataService("user");

var myrtmp:RTMPChannel = new RTMPChannel("my-rtmp",
"rtmp://myremoteserver:2038");

ds.channelSet = new ChannelSet();
ds.channelSet.addChannel(myrtmp);

ds.fill(users);
}

private function addUser():void
{
var ur:User = new User();
ur.id = 7;
ur.name = "test";

ds.createItem(ur);
}
