    Error: Only a client can stream data.

    When I open more than 1 tab in IE(Chrome or Firefox) then only tab can be streaming data. Others tab is not streaming data. Why?

    This is my code in class StockBoardAdapter:

    Code:
    public class StockBoardAdapter : IDataProvider
    {    
        public StructFileManager m_PRSFileStructManager = null;

            _myGlobal._myGlobal = itemName.Substring(4);
            
            Thread t = new Thread(new ThreadStart(Run));
            t.Start();

    hi,

    the important bits are on the index.html file.
    Do you see any alert on your pages?
    Do you see any javascript error?
    Can you see the control requests for your second tab on the server?
    Is it possible that the problem is just that you don't ask for the snapshot for the table "a"?

    what about the snapshot setting?
    If you open the application in a completely different browser instead of opening it in another tab, does it receive data?

    Probably what happens is that the first client that connects receives the snapshot directly from the adapter. Once the item is subscribed the snapshot is handled by the server that does not send it unless you ask for it. If you don't ask the snapshot to the server it will send only the new updates but not the current status.

    to fix your app, where you call



    you should add



    please read the setSnapshotRequired documentation and the General Concepts.pdf file available under the LS_HOME/DOCS-SDKs folder
