Thanks a lot Mehfuz, I realised what it was, just not why it was happening. Thanks for the patch though.
Cheers
Paul

Hi,

I'm a newbie to ASP.NET MVC and am getting the following error when I run the app. The strange thing is that when I set a breakpoint on the line preceding the one that gives the error (HttpContextBase context = filterContext.HttpContext;) and step through the code from there on, the error goes away and it works fine! By th way I am using MVC Release version 1

Any ideas?

Thanks
Paul

Thanks very much for sharing this. I was searching for an update for Asp.Net MVC beta using NUnit to test Controllers and found this project. Upon inspecting the code, it is immediately apparent that the author(s) have an exceptional handle on good design and architecture. It certainly accomplished my goal of provinding a strong example for testing controllers. I also learned a bit from looking at how the Models are organized (ViewData classes). Definitely a more flecxible approach that my giant, compound view data classes and separate repositories. I didn't take the appropriate time to design my ViewData model up front and now I have some work to do :)

Server Error in '/' Application.

Runtime Error

Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>
