I've a web using asp.net MVC 3 with razor.
In one view I'm having an odd error with the checkbox helper.
Here is the razor code:
#Html.CheckBox("rememberPassword", Model.RememberPassword, new { tabindex = "4", style = "width:15px" })
The property in the model (which I set to true in the Model constructor):
public bool RememberPassword { get; set; }
And the logged error:
2012-04-13 01:20:33.334 [13 ] Error - Reference: 0413-012033-334 - Global site error, page: /es/login

Why is this happening?
Note:
It keeps getting odder and odder. As magically as the error started appearing (in a productive site some day without any updates or releases) not it has stopped. It's been three days without the error. However, I'd still like to know why was it.
It had nothing to do with the way of creating the checkbox. In some very odd scenarios (which I had forgotten at all), this forms may be submitted (from other sites) without this parameter. In this cases the bool field was trying to obtained from the string "-1".
One way of resolving this issue (that I have discovered to be a good practice) is to avoid "not-nullable" fields in the Model.
Just try this instead
Html.CheckBoxFor(model => model.RememberPassword , chkHtmlAttributes)
And define the chkHtmlAttributes to these
tabindex = "4", style = "width:15px"

I have a class Event with a property of the type DbGeography.
public class Event
{
public long Id { get; set; }
public DateTime Date { get; set; }
public DbGeography Location { get; set; }
}
In the class DatabaseHelper I try to load data from a server.
public async Task<IEnumerable<Event>> GetEventsAsync()
{
var uri = new Uri(string.Format(Constants.EventsUrl, string.Empty));
var content = await _client.GetStringAsync(uri);
IEnumerable<Event> events = JsonConvert.DeserializeObject<List<Event>>(content);
return events;
}
But an error is thrown:
Newtonsoft.Json.JsonSerializationException: Error getting value from 'WellKnownValue' on 'System.Data.Entity.Spatial.DbGeography'.
I did found out that I should use a custom JsonConverter.
// DbGeographyConverter.cs
public class DbGeographyConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return objectType.IsAssignableFrom(typeof(string));
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
JObject location = JObject.Load(reader);
JToken token = location["Geography"]["WellKnownText"];
string value = token.ToString();
System.Data.Entity.Spatial.DbGeography converted = System.Data.Entity.Spatial.DbGeography.PointFromText(value, 4326);
return converted;
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
// Base serialization is fine
serializer.Serialize(writer, value);
}
}
But when calling http://localhost:57609/api/events, which returns list of Event objects, the following error is thrown:

What could be the problem?
Problem is you are referencing Newtonsoft.Json 10.0.0.0
Could not load file or assembly 'Newtonsoft.Json, Version=10.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference.
It seems version 10.0.0.0 is no longer available on NuGet servers, thus you can't have it locally. No where to download from. Try to update/install existing version. It might work then.
Install-Package Newtonsoft.Json -Version 10.0.3
I recently have this strange issue with IIS. We have an ASP.NET website and recently it fails after an application pool recycle. When I stop the applicationpool, clear the "ASP.NET Temporary Files" and restart the applicationpool. It works again. When i manually recycle it, it breaks again. I can reproduce this every time. The big problem is that our web application recycles every night.
Can I in some way prevent the usage of these ASP.NET Temporary Files? Or how could i fix this issue.
[Edit]
this is a screenshot of the error:

So I have a "Register" view (that maps to a RegisterController), which is a simple form for people to register in my service. Given that the form's method is POST, then I can name both actions of the controller (the one that shows the form, and the one that receives its submission) the same name, but discriminate them via the [HttpPost] attribute, this way:
open System
open System.Web
open System.Web.Mvc
open System.Net
open System.Threading
open System.Configuration
[<HandleError>]
type RegisterController() =
inherit Controller()
member this.Index (guid: string) =
let model = new RegisterModel(guid)
this.View("Register", model) :> ActionResult
[<HttpPost>]
member this.Index
(guid: string, password: string, passwordRetry: string) =
if not (password.Equals(passwordRetry)) then
raise(new Exception("Passwords must be the same"))
WebDbAccess.SetNewPassword guid password
RedirectResult("/") :> ActionResult
This works perfectly.
However, I just tried to use this same technique in the Home view of my app (for the Login functionality), and it doesn't work! It throws this:
The current request for action 'Index' on controller type 'HomeController' is ambiguous between the following action methods:

What's the difference between the 2 cases? I don't get it.
The HomeController's implementation is:

open System.Web
open System.Web.Http

this.View() :> ActionResult
[<HttpPost>]

RedirectResult("lobby") :> ActionResult
RedirectResult("loginError") :> ActionResult
#nemesv was right, I had to fully qualify HttpPost with System.Web.Mvc.HttpPost because otherwise it would use System.Web.Http.HttpPost!!
I've run into an interesting exception. On one of my production servers, occasionally I'll get the following exception.

at sftControls.SearchListLandingPage.getHtml(IXPathNavigable document, String Xsl, String headerLinks)
Opening up the IL and looking through each method suggests that the DocumentXPathNavigator => this.document is null. What's strange is that I can in no way duplicate this issue locally or on our test servers.
A little background, and this might be the key...
This is a web application(running .Net 3.5) that caches the XmlDocument that gets passed into XslCompiledTransform.Transform(). Our caching is serviced through a distributed cache server. The XmlDocument is serialized and cached so a reference to the specific object should not continue to exist. That leads me to believe that either something is explicitly preventing this.document from ever being set when the implicit XmlDocument -> DocumentXPathNavigator happens or some reference somewhere is removed while the Transform() is running. Either way I am perplexed.
So, I guess my questions are:
Has anyone else seen this before?
Does anyone know what could be causing it or how to deal with it?
Thanks
EDIT:
After further thinking about this, the only thing that would make sense is that it's a race condition. The caching appliance is somehow expiring the object while the application is using the object.
EDIT/EDIT:
.Net 3.5, the assembilies being referenced above are 2.0
In case anyone has this same exception.
We found that this exception occurs when xmldocument.HasChildNodes is false or DocumentElement is null. Verifying that the document has elements, BEFORE querying on it, resolves this.
I experienced a very similar exception inside an XslCompiledTransform:
System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.NullReferenceException: Object reference not set to an instance of an object.

Like you, we were passing an XPathDocument to the Xsl transform and the XPathDocument was being retrieved from distributed cache. Unfortunately, an XPathDocument is not serializable and therefore unusable after it is retrieved from the distributed cache. We fixed the problem by using an XmlDocument instead of an XPathDocument and using SerializedXmlDocument to serialize and deserialize it as follows:
public static XmlDocument CachedXmlDoc
{
get
{
lock (_locker)
{
// maintain the Part XmlDocument in the distributed cache so that it can be reset from any production instance
SerializedXmlDocument serializedXmlDoc = Reliable.Application[Global.CACHED_XML_DOC] as SerializedXmlDocument;
XmlDocument cachedDoc = (serializedXmlDoc == null) ? null : serializedXmlDoc.XmlDocument;
if (cachedDoc == null)
{
cachedDoc = myController.CreateXmlDoc();
Reliable.Application[Global.CACHED_XML_DOC] = new SerializedXmlDocument(cachedDoc);
}
return cachedDoc;
}
}
set
{
lock (_locker)
{
if (value == null)
{
Reliable.Application[Global.CACHED_XML_DOC] = null;
}
else
{
throw new Exception("Tried to set the cached XmlDocument to something other than null.");
}
}
}
}
This is the error I'm getting using MVC2:
Either ErrorMessageString or ErrorMessageResourceName must be set, but not both.
It is coming from the [Required] Validation DataAnnotation.
Stack trace:

I've boiled my view model down to this(it breaks any time there is a [Required] attribute, works fine without):
[Required(ErrorMessage = "")]
[DataType(DataType.Text)]
[DisplayName("Property Name")]
public string MyProperty { get; set; }
My controller returns an empty ViewModel, and the form in the view is completely blank...just a submit button.
In my case, I have write ErrorMessage = null, example :
[EmailAddress(ErrorMessageResourceName = "FORM_FIELD_VALIDATION_EMAIL", ErrorMessageResourceType = typeof(App_GlobalResources.Common.View_Common_Forms), ErrorMessage = null)]
ErrorMessage = " " don't work.
The problem lies in setting the ErrorMessage to a blank string. I would have to assume that at some point there is a check for String.Empty in the MVC code that is causing problems.
Setting the ErrorMessage to " "(one space) solved the issue.
My guess is [DataType(DataType.Text)] has a validation message defined in resources (in System.ComponentModel.DataAnnotations.Resources) and the existence of that and your [Required] is causing this InvalidOperationException. Try Removing [DataType] or [Required] and see if the exception goes away.
I had a simmilar issue with a custom ValidationAttribute.
In the IsValid method I was setting the ErrorMessage. The fix was to remove the assignation to the ErrorMessage propety...
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
//code before ...
this.ErrorMessage = this.FormatErrorMessage(validationContext.DisplayName); //NOT GOOD...
ValidationResult validationResult = new ValidationResult(this.ErrorMessage, //And using the ErrorMessage Here...
new[] { validationContext.MemberName });
return validationResult;
}
I was writting Unit test and they were pasisng only if i was running/debugging one by one. But when I click "Run All", only the first one was passing? They are not Linked in any ways...
I also tried https://stackoverflow.com/a/20848920/4798459
Didn't work either.
So yeah, the fix was to remove the assignation to the ErrorMessage propety!
