Value cannot be null. Parameter name: umbracoContext

Hi,

I just created a url redirect with URL Tracker:

However, when I enter the old url in the browser, I'm getting this ysod:

I'm using version 2.2.3 of URL Tracker. My Umbraco install is v6.1.5

greetings,

Anthony

This is the same as you've posted before, which you fixed right? http://our.umbraco.org/projects/developer-tools/301-url-tracker/version-2/45314-issue-witch-Umbraco-615

Hi Stefan,

Yes, but that was due to a missing querystring. Now I don't have a querystring, the url that needs to be redirected is just: http://www.cjs.ugent.be/about_us.html

To be sure, I downloaded a fresh Umbraco 6.1.5 install and copied all dll starting with umbraco.xxxxx to the bin folder of my website, but it didn't solve the issue.

Well this is freaky...
I'm running the UrlTracker on one of my v6.1.6. sites fine. But I've installed it in a clean 6.1.6. instance and I got the same exception as you.
I haven't got a clue how this can happen, maybe after this weekend. I'll call in help from Shannon too via Twitter, maybe he knows what's happing.

Here's the clean install with the UrlTracker and one entry: https://mega.co.nz/#!x1xlSDRQ!ALQxW1ZxULrqsFzkQ5KWukp184FNo86uS1a7TpxAo
The DB is included as SQL 2008 R2 backup in "App Data" (Umb615.bak).
The connection string needs updating too ofcourse ;-)
If you visit the URL of the entry (/about_us.html) you'll see the error.

The problem is that this request is for an ".html" page

To save on a lot of processing when running integrated mode, we check: uri.IsClientSideRequest() which includes these files:

var toIgnore = new[] { ".js", ".css", ".ico", ".png", ".jpg", ".jpeg", ".gif", ".html", ".svg" };

In which case we do not create an UmbracoContext or attempt to process the request as if it is part of Umbraco

Thanks for the clarification Shannon.
I've release version 2.2.6, which should fix this issue. Could you try that version Anthony?

For reference, this is the code I've added for filling the UmbracoContext.Current when empty:

if (!_umbracoAssemblyInitialized)
{
    IEnumerable<Assembly> umbracoCoreAssemblies = AppDomain.CurrentDomain.GetAssemblies().Where(x => x.FullName.StartsWith("umbraco, "));
    if (umbracoCoreAssemblies != null && umbracoCoreAssemblies.Any())
        _umbracoAssembly = umbracoCoreAssemblies.OrderByDescending(x => x.ImageRuntimeVersion).First();
}
if (_umbracoAssembly != null)
{
    Type umbracoContextType = _umbracoAssembly.GetType("Umbraco.Web.UmbracoContext");
    if (umbracoContextType != null)
    {
        object umbracoContextCurrent = umbracoContextType.GetProperty("Current").GetValue(null, null);
        if (umbracoContextCurrent == null)
        {
            MethodInfo ensureContextMethod = umbracoContextType.GetMethod("EnsureContext", new Type[] { typeof(HttpContextBase), typeof(ApplicationContext) });
            if (ensureContextMethod != null)
                ensureContextMethod.Invoke(null, new object[] { new HttpContextWrapper(HttpContext.Current), ApplicationContext.Current });
        }
    }
}

_umbracoAssemblyInitialized = true;

Hi Stefan,

Ok, I'll install Url Tracker 2.2.6 and let you know if it solved the problem.

Thanks for looking into this,

Anthony

Hi Stefan,

I installed Url Tracker 2.2.6 on my local machine.

Then I created the redirect for about_us.html

when I go to http://localhost/aboutus.html, I'm getting a blank page, with in the address bar the url: http://localhost/aboutus.html

I just add:
```
<add key="urlTracker:enableLogging" value="true" />
```
to the web.config of my local site

Then I browsed to
```
"http://localhost/about_us.html
```
and now it redirected to
```
http://localhost/about_us.aspx
```
maybe it was a cache thing :)

I'll install Url Tracker 2.2.6 on my production machine now. Can I just install it over my existing install of Url Tracker ?

sure, I just upgraded to Url Tracker 2.2.6. Is it normal that the installation wizzard says
```
"Previous version checked successfully"
```
and then
```
"Previous version not found"
```

Yeah my fix wasn't compatible with umbraco v4, so I had to remove it.
Haven't had the time to look into this again unfortunately, but the good news is; I do have ideas and code examples to fix this, so it will get fixed any time soonish.

What's the best way to handle redirects on HTML pages in Umbraco 6.1.6 currently? Is this possible? Thanks :) Laurence

Hey!

I'm getting the same error as mentioned earlier in this post.

When trying to handle a page with a *.html extension, it looks like the UmbracoContext.Current is empty. Shannon mentioned that *.html are ignored by Umbraco by default.

I'm running 2.3.1.

Exception information: 
Exception type: ArgumentNullException 
Exception message: Value cannot be null.

Could you create a new topic for this issue and mention a bit more information about your set-up (like your umbraco URL settings) and post the entry from the DB?
