We have a  Sharepoint 2007 and k2 blackpearl, within sharepoint we run an aspx page. This page updates sharepoint user permissions and sharepoint list items based upon user input. We want to check that the k2 process that we have started to do the above completes successfully. we use the startprocessinstance function with synchronous true and we are returned an error. so, we always get an exception whether the process completes successfully or not.

 Can anyone please help, sample of our code is below

try
            {

                string _message = "";
                SourceCode.Hosting.Client.BaseAPI.SCConnectionStringBuilder connectionString =
                        new SourceCode.Hosting.Client.BaseAPI.SCConnectionStringBuilder();

                connectionString.Authenticate = true;
                connectionString.Host = "localhost";
                connectionString.Integrated = true;
                connectionString.IsPrimaryLogin = true;
                connectionString.Port = 5252;
                connectionString.UserID = "administrator";
                connectionString.WindowsDomain = "k2demo";
                connectionString.Password = "k2pass";
                connectionString.SecurityLabelName = "K2"; //the default label

                SourceCode.Workflow.Client.Connection connection = new SourceCode.Workflow.Client.Connection();

                //open connection to K2 server
                connection.Open("localhost", connectionString.ToString());

                //create process instance
                ProcessInstance processInstance = connection.CreateProcessInstance("K2InviteUserToBidReviewTestErrorProcess");

                //populate data fields                             
                //processInstance.DataFieldsb"siteName"].Value = SPContext.Current.Web.Url;
                //processInstance.DataFieldst"listUsers"].Value = users;
                //processInstance.DataFieldsÂ"GateLibraryName"].Value = libraryName.Trim();
                //processInstance.DataFieldsb"reviewURL"].Value = url.Trim();

                ////set process folio
                //processInstance.Folio = _processFolio + System.DateTime.Today.ToString();

                //start the process
                connection.StartProcessInstance(processInstance, true);

                if (processInstance.Status1.Equals(ProcessInstance.Status.Completed))
                {
                    _message = "Gate has been invited for review.";
                    //lblMessage.Text = libraryName + " Gate have been invited for review.";
                }
                else if (processInstance.Status1 == ProcessInstance.Status.Error)
                {
                    _message = "This process is in an error state -> Gate was not invited for review.";
                    throw new System.Exception(_message);
                }
                //_message = processInstance.Status1.ToString();
            }
            catch (Exception exp)
            {
               response.write(exp.ToString());

            }
           

The Error we get is:
