WF

i have created WOrkflow Service Project having parallel workflow in it that have state machine (for creating new workflow) and while activity for fetching workflow status. i have used page url and current state variable at global level , which are set by state machine as per state and used by other activities say GetWOrkflowStatus in its response. ..

while calling workflow i passes SIte Id, RequestId and so on..


i have used below code to call the service and all are workfind fine....

private IWorkflowservice GetServiceFromChannel()
{
    BasicHttpBinding myBinding = new BasicHttpBinding();

    EndpointAddress myEndpoint = new EndpointAddress("http://localhost:64905/Service/Service1.xamlx");

    ChannelFactory<ServiceContract.IWorkflowservice> myChannelFactory = new ChannelFactory<ServiceContract.IWorkflowservice>(myBinding, myEndpoint);


    return myChannelFactory.CreateChannel();
}

/// <summary>
/// Create New Workflow Instance
/// </summary>
/// <returns></returns>
public ActionResult Create()
{

    IWorkflowservice service = GetServiceFromChannel();

    RequestId = Guid.NewGuid();

    WorkflowRequest requestData = new WorkflowRequest();
    requestData.RequestID = RequestId.ToString();
    requestData.SiteID = 123;

    WorkflowResponce response = service.InitiateWorkflow(requestData);


    RequestDataModel model = new RequestDataModel();
    model.RequestId = RequestId;
    model.Message = GetMessage(response);


    return View(model);
}



public ActionResult GetStatus()
{
    IWorkflowservice service = GetServiceFromChannel();

    WorkflowRequest requestData = new WorkflowRequest();
    requestData.RequestID = RequestId.ToString();

    WorkflowResponce response = service.GetWorkflowStatus(requestData);

    RequestDataModel model = new RequestDataModel();
    model.Message = GetMessage(response);
    model.RequestId = RequestId;

    return View(model);
}

i am facing problems in following cases:
1. Get all workflows with are in specified State and in Specified Site. returned Data must contain Request Id and page url(global variable)
i have tried various tracking but all no luck..
