BackgroundWorker not working for Perforce API

Question

I am implementing Perforce API in my application. For few long processes, I am trying to implement backgroudworker. I have done the implementation before many times, I know the in and outs of the BGW, but this time I am just not able to get results.

public P4()
        {
            bw.WorkerReportsProgress = true;
            bw.WorkerSupportsCancellation = true;
            bw.DoWork += new DoWorkEventHandler(bw_DoWork);
            bw.ProgressChanged += new ProgressChangedEventHandler(bw_ProgressChanged);
            bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted);

        }

private void bw_DoWork(object sender, DoWorkEventArgs e)
        {
            BackgroundWorker worker = sender as BackgroundWorker;            

            Recordset = p4.Run(p4command, p4args);
        }

P4 is my constructor initializing BGW. I am calling it normally via RunWorkerAsync() method. bw_DoWork suppose to run p4.Run() but my Recordset is null (means command is not running). About p4command, its a global string containing command such as "integrate" and p4args is a global array containing arguments for the command, both are initialized from the base function.

Any idea what I am missing? (I also have bw_RunWorkerCompleted() which runs perfectly after bw_DoWork skips p4.run)

Thanks

EDIT: All functions related to BGW are in a separate class, P4, which has nothing to do with any GUI operations. I am calling P4.integrate() from a GUI which in turn call BGW. When I place P4.run() directly into P4.integrate() I get my results in Recordset, but placing this same command into bw_DoWork() seems not to work.

Async call is in P4 class, inside P4.integrate().

Thanks

Can you get it to work on the GUI thread outside of the background worker? If so...

Are the commands being used, the references, located on the GUI thread? Even though one is reading information, cross thread access is still a consideration. I had run into a linq issue failure C# WPF: Linq Fails in BackgroundWorker DoWork Event when using a background worker and this seems similar.

Update

Where is your run worker async call?
