I'm just starting to use Glimpse with my MVC5 project and have run into an issue when I use Postal to send an email without disabling Glimpse. I've been able to narrow it down to an issue with both packages - it doesn't occur if the Glimpse cookie has not been turned on.
In Fiddler, I checked the difference between the two. When it threw the exception, the cookie was
glimpsePolicy=On
when it worked (Glimpse was off) there were two cookies
glimpseId=FBar; glimpsePolicy=
The exception I get is
System.ArgumentNullException: Value cannot be null.

I created a quick action to test it. The controller code is:
public void TestEmailExt()
{
var confirmationToken = "ConfirmationToken";
var Phone1 = "**********";
dynamic email = new Email("RegEmail");
email.To = "**#gmail.com";
email.UserName = "UserName";
email.ConfirmationToken = confirmationToken;
email.Phone = Extensions.Right(Phone1, 4);
if (email.To.Contains("#mydomain"))
email.From = INTERNAL_EMAIL_FROM;
else
email.From = EXTERNAL_EMAIL_FROM;
email.Send();
}
The reason this fails is because the Postal library creates its own HttpContext instance while rendering the email view as the decompiled CreateControllerContext method inside Postal's EmailViewRenderer class shows:
private ControllerContext CreateControllerContext()
{
HttpContextWrapper httpContextWrapper = new HttpContextWrapper(new HttpContext(new HttpRequest("", this.UrlRoot(), ""), new HttpResponse(TextWriter.Null)));
RouteData routeData = new RouteData();
routeData.Values["controller"] = (object) this.EmailViewDirectoryName;
return new ControllerContext(new RequestContext((HttpContextBase) httpContextWrapper, routeData), (ControllerBase) new EmailViewRenderer.StubController());
}
This means that the setup that Glimpse does at BeginRequest is completely removed, while the hooks are still in place to intercept MVC related calls.
We've had a similar issue where I gave a similar response to why this is not working.
UPDATE :
I mentioned above that a similar issue had been reported previously, but while I was trying to find a more appropriate solution, it seemed that this case is slightly different in that respect that the other similar issue actually executes a controller with the freshly created context resulting in a NullReferenceException in Glimpse specific code, while here we get a NullReferenceException inside MVC specific code, albeit triggered by Glimpse.
System.ArgumentNullException: Value cannot be null.
Parameter name: controllerContext
at System.Web.Mvc.ChildActionValueProviderFactory.GetValueProvider(ControllerContext controllerContext)
And the exception we get here is because the ControllerContext property on the StubController instance (created inline) is null, which would normally be set when executing the controller (which is not the case here).
So the workaround that I proposed below still applies, but can be avoided if the code of the CreateControllerContext() above is slightly modified:
private ControllerContext CreateControllerContext()
{
HttpContextWrapper httpContextWrapper = new HttpContextWrapper(new HttpContext(new HttpRequest("", this.UrlRoot(), ""), new HttpResponse(TextWriter.Null)));
RouteData routeData = new RouteData();
routeData.Values["controller"] = (object) this.EmailViewDirectoryName;
// MODIFIED
var stubController = new EmailViewRenderer.StubController();
var controllerContext = new ControllerContext(new RequestContext(httpContextWrapper, routeData), stubController);
stubController.ControllerContext = controllerContext;
return controllerContext;
}
I've created an issue for this on the Postal issue tracker
END OF UPDATE
I think the best solution, for now, is to disable Glimpse while calling into Postal and restore normal Glimpse behavior back again afterwards. We might include this one way or the other into the Glimpse Core library in one of the upcoming releases as it seems that disabling Glimpse during a specific part of the request processing logic doesn't seem to be that uncommon, but for now the following snippet might help you (beware it makes use of a Glimpse internal key which is not guaranteed to be there in an upcoming release)
public class GlimpseSuppressionScope : IDisposable
{
private const string GlimpseRequestRuntimePermissionsKey = "__GlimpseRequestRuntimePermissions";
private readonly HttpContext currentHttpContext;
private readonly RuntimePolicy? currentRuntimePolicy;
private bool disposed;
public GlimpseSuppressionScope(HttpContext currentHttpContext)
{
if (currentHttpContext == null)
{
throw new ArgumentNullException("currentHttpContext");
}
this.currentHttpContext = currentHttpContext;
this.currentRuntimePolicy = this.currentHttpContext.Items[GlimpseRequestRuntimePermissionsKey] as RuntimePolicy?;
this.currentHttpContext.Items[GlimpseRequestRuntimePermissionsKey] = RuntimePolicy.Off;
}
~GlimpseSuppressionScope()
{
this.Dispose(false);
}
public void Dispose()
{
this.Dispose(true);
GC.SuppressFinalize(this);
}
private void Dispose(bool disposing)
{
if (!this.disposed)
{
if (disposing)
{
if (this.currentHttpContext != null)
{
this.currentHttpContext.Items.Remove(GlimpseRequestRuntimePermissionsKey);
if (this.currentRuntimePolicy.HasValue)
{
this.currentHttpContext.Items[GlimpseRequestRuntimePermissionsKey] = this.currentRuntimePolicy.Value;
}
}
}
this.disposed = true;
}
}
}
which you can then use in your controller action method as shown below:
public void TestEmailExt()
{
using (new GlimpseSuppressionScope(System.Web.HttpContext.Current))
{
var confirmationToken = "ConfirmationToken";
var Phone1 = "**********";
dynamic email = new Email("RegEmail");
email.To = "**#gmail.com";
email.UserName = "UserName";
email.ConfirmationToken = confirmationToken;
email.Phone = Extensions.Right(Phone1, 4);
if (email.To.Contains("#mydomain"))
email.From = INTERNAL_EMAIL_FROM;
else
email.From = EXTERNAL_EMAIL_FROM;
email.Send();
}
}

I'm trying to write a simple RTD client to start with something, but I seem not able to make the initial connection. I have found some examples on the web, and best seemed to be this RTD client in C# gist.
Having this on MS-Excel: =RTD("rtdtrading.rtdserver",, "WINZ20_F_0", "HOR") - formula works on Excel and pulls fresh data.
In the code from the gist above, I then tried to instantiate the object with:
var handler = new RtdClient("rtdtrading.rtdserver");
So far, so good. But then, when I try to
var valList = handler.GetValue(new object[] { "WINZ20_G_0", "HOR" });
I get a big Catastrophic failure (0x8000FFFF (E_UNEXPECTED)) from IRtdServer.ConnectData(Int32 topicId, Object[]& parameters, Boolean& newValue), line 24 in the code above.
If I try to use new string[] { "WINZ20_G_0", "HOR" });, then the error changes to Specified array was not of the expected type, happening a bit deeper, but I believe still before ConnectData() is actually run, as the call stack suggestes:
at System.StubHelpers.MngdSafeArrayMarshaler.ConvertSpaceToNative(IntPtr pMarshalState, Object& pManagedHome, IntPtr pNativeHome)
at ProfitRTDAnalyzer.Program.IRtdServer.ConnectData(Int32 topicId, Object[]& parameters, Boolean& newValue)
I can't seem to properly identify how to handle this. Changing the object[] refs to string[] where they relate to those arguments (the topic list), didn't help either (still _array was not of expected type).
According to MS documentation, ConnectData() receives as second parameter a single-dimensional array of strings, so I don't know what is wrong here.
to solve this problem, I have done that:
Create a new class to implement UpdateEvent:
public class UpdateEvent : IRTDUpdateEvent
{
public long Count { get; set; }
public int HeartbeatInterval { get; set; }
public UpdateEvent()
{
// Do not call the RTD Heartbeat()
// method.
HeartbeatInterval = -1;
}
public void Disconnect()
{
// Do nothing.
}
public void UpdateNotify()
{
Count++;
}
}
and then, replace it into GetRtdServer function
IRtdServer GetRtdServer() {
if (_rtdServer == null) {
Type rtd = Type.GetTypeFromProgID(_rtdProgId);
_rtdServer = (IRtdServer) Activator.CreateInstance(rtd);
// Create the updateEvent.
UpdateEvent updateEvent = new UpdateEvent();
_rtdServer.ServerStart(updateEvent);
}
return _rtdServer;
}
I am trying to insert a new record into a custom table in the database. This is being performed through a graph extension onto the SO graph. The code is as follows:
public PXAction<PX.Objects.SO.SOOrder> addToDatabase;
[PXButton(CommitChanges = true)]
[PXUIField(DisplayName = "Send to Manufacturing")]
protected void AddToDatabase()
{
try
{
Flow2 graphWO = PXGraph.CreateInstance<Flow2>();
EMPWorkOrder wo = null;
foreach (PXResult<SOLine, InventoryItem> line in PXSelectJoin<SOLine, LeftJoinSingleTable<InventoryItem, On<InventoryItem.inventoryID, Equal<SOLine.inventoryID>>>,
Where<SOLine.orderNbr, Equal<Current<SOOrder.orderNbr>>>>.Select(Base, Base.Document.Current.OrderNbr))
{
PXCache sender = Base.Transactions.Cache;
SOLine soLine = (SOLine)line;
InventoryItem item = (InventoryItem)line;
SOLineExt lineExt = sender.GetExtension<SOLineExt>(soLine);
if (lineExt.UsrisSentToManufacturing != true)
{
wo = new EMPWorkOrder();
wo.Soid = Base.Document.Current.OrderNbr;
wo.ItemCD = item.InventoryCD;
wo.LineNbr = soLine.LineNbr;
wo.QtyReceived = 0;
wo.DateReceived = null;
wo.QtyComplete = 0;
wo.QtySentToInventory = 0;
wo.RouteId = "0";
wo.KitId = -1;
wo.IsStarted = false;
wo.NoteID = Guid.NewGuid();
graphWO.Document.Insert(wo);
graphWO.Actions.PressSave();
graphWO.Clear();
}
}
throw new PXException("Successfully moved to Manufacturing");
}
}
When executing the code, the error I receive is the following:
Error#14: Inserting 'EMPWorkOrder' record raised one or more errors. Please review.
When I go into the trace, this is the information it gives me:
12/16/2016 1:44:23 PM Error:
Error #14: Inserting 'EMPWorkOrder' record raised one or more errors. Please review.

at PX.Web.UI.PXBaseDataSource.ExecuteSelect(String viewName, DataSourceSelectArguments arguments, PXDSSelectArguments pxarguments)
Is there any reason that my record wouldn't be inserting into the custom table I made? If you need any other information to develop a resolution to this issue, please feel free to ask.
Eric, you most likely get this error because of some empty field or fields (with no value or null value assigned) decorated with the PXDefaultAttribute. While running the code under debugger, you should get access to a more detailed exception through the InnerException property of the originally thrown exception.
On a side note, let me also advise you to add SOLine.orderType field in Where clause of your BQL query in the beginning of action delegate, as there are 2 key fields defined for the SOOrder DAC has: OrderType and OrderNbr
I am using this code to try and render a razor partial view as a string for the purposes of sending an email.
public static string RenderPartialToString(
string userControlPath,
object viewModel,
ControllerContext controllerContext,
TempDataDictionary tempData)
{
using (var writer = new StringWriter())
{
var viewDataDictionary = new ViewDataDictionary(viewModel);
var view = new WebFormView(controllerContext, userControlPath);
var viewContext = new ViewContext(
controllerContext,
view,
viewDataDictionary,
tempData,
writer
);
viewContext.View.Render(viewContext, writer);
return writer.GetStringBuilder().ToString();
}
}
The problem is that I get the follow error:
must derive from ViewPage, ViewPage<TModel>, ViewUserControl, or ViewUserControl<TModel>. Stack Trace: at System.Web.Mvc.WebFormView.RenderView(ViewContext viewContext, TextWriter writer, Object instance) at .... RenderPartialToString
How would I fix that ?
Indeed, WebFormView doesn't inherit from the mentioned classes, just IView. I did a little Google research and got a prototype working. This page was the most helpful.
I created an empty MVC3 application and created the following HomeController. When I run the application, the page shows the rendered string. The resultAsString variable shows how to capture the rendering as a string.
using System;
using System.IO;
using System.Web.Mvc;
public class HomeController : Controller
{
public ActionResult Index()
{
var result = RenderPartial(this.ControllerContext, "This is #DateTime.Now right now");
var resultAsString = result.Content;
return result;
}
private ContentResult RenderPartial(ControllerContext controllerContext, string template)
{
var temporaryViewPath = string.Format("~/Views/{0}.cshtml", Guid.NewGuid());
using (var stringWriter = new StringWriter())
{
using (var fileStream = System.IO.File.Create(Server.MapPath(temporaryViewPath)))
{
using (var streamWriter = new StreamWriter(fileStream))
{
streamWriter.WriteLine(template);
streamWriter.Close();
}
fileStream.Close();
}
var razor = new RazorView(controllerContext, temporaryViewPath, null, false, null);
razor.Render(new ViewContext(controllerContext, razor, new ViewDataDictionary(), new TempDataDictionary(), stringWriter), stringWriter);
System.IO.File.Delete(Server.MapPath(temporaryViewPath));
return Content(stringWriter.ToString());
}
}
}
I have a WCF REST service that takes some parameters and sends an email. The template for the email is an MVC3 action. Essentially I want to render that action to a string.
If it were an ASP.NET WebForm, I could simply use Server.Execute(path, stringWriter, false). However when I plug in the path to my action, I get Error executing child request.
I have full access to HttpContext from my service (AspNetCompatibilityRequirementsMode.Allowed).
I know there are other answers out there for rendering actions to strings from within the context of a controller. How do I do this when I'm outside that world, but still on the same server (and, for that matter, in the same app)?
I cobbled together an answer based on several different google searches. It works, but I'm not 100% sure it's as lean as it could be. I'll paste the code for others to try.
string GetEmailText(TemplateParameters parameters) {
// Get the HttpContext
HttpContextBase httpContextBase =
new HttpContextWrapper(HttpContext.Current);
// Build the route data
var routeData = new RouteData();
routeData.Values.Add("controller", "EmailTemplate");
routeData.Values.Add("action", "Create");
// Create the controller context
var controllerContext = new ControllerContext(
new RequestContext(httpContextBase, routeData),
new EmailTemplateController());
var body = ((EmailTemplateController)controllerContext.Controller)
.Create(parameters).Capture(controllerContext);
return body;
}

I've created a BCS service and created an external list from the BCS content-type.
I have then tried to add a SPGridView control to a webpart. I am getting an exception as soon as I call my SPGridview's DataBind() method, here is what the code looks like:

this.web = this.site.OpenWeb();
this.we_list = this.web.Lists["BCSList"];
this.spdata = new SPDataSource();
Controls.Add(this.spdata);

Dictionary<string, string> listFields = new Dictionary<string, string>();
listFields.Add("CompanyName", "Company Name");
listFields.Add("ContactDetails", "Contact Details");
listFields.Add("ProjectDescription", "Description");
foreach (var row in listFields)
{

boundField.HeaderText = row.Value;
boundField.DataField = row.Key;
this.gv.Columns.Add(boundField);
}
}
protected override void RenderContents(HtmlTextWriter writer)
{
if (!Page.IsPostBack)
{
this.BindColumns();
this.gv.DataBind();
}
this.gv.RenderControl(writer);
}
}
}
The DataBind() method is throwing the following exception:

I have verified that this.we_list is not empty (In Visual Studio debugger's locals tab, I can see this.we_list.Items.Count is set to 99, although this.we_list.ItemCount is set to 0.)
Also, that all seems to work okay against non-external lists, but I see nothing in the docs about external lists not being supported in SPGridView or SPDataSource, and the exception makes no mention of external lists not being supported. Has anyone run into this issue?
This seems to be a possible Sharepoint Server 2010 bug (I'm using Sharepoint Server 2010 Enterprise Edition). Ultimately, I solved the problem by adding a to_datatable() conversion method to my BCS service entity that simply uses the statis ReadList() method, collects its output, and inserts the data into a DataTable object.
