Getting object reference not set to instance of object when finishing setup...

…who is rpaquay? That is not a local user on this machine...

 

A - Rpaquay is a developer on the Orchard team.

B - I am not getting the NullReferenceException when setup completes.

I enlisted in the source code by following the steps at:

http://orchard.codeplex.com/wikipage?title=enlist&referringTitle=Documentation

How did you acquire Orchard? Did you download OrchardIIS.zip, OrchardIIS_64.zip, OrchardSource.zip, or did you enlist in the source code using a Mercurial client?

 

 

Answer 2

I installed it using the Platform Installer...

 

I will try to install manually... but I do get the error on two different machines.

Answer 3

We couldn't reproduce that. Can you give some more details about your setup (what version of IIS, MVC, etc.)? Can you also retrace the exact steps you took to install the app and write them here?

Thanks!

Answer 4

After the initial setup populates the database, Orchard 1.3.10 will fail with…

[NullReferenceException: Object reference not set to an instance of an object.]
   Orchard.Themes.Preview.PreviewTheme.GetPreviewTheme() +52
   Orchard.Themes.Preview.PreviewThemeFilter.OnResultExecuting(ResultExecutingContext filterContext) +58

…if session state is turned off.

One way to reproduce this is to have a web.config in the root of your web site that has…

    <system.web>
        <sessionState mode="Off" />
    </system.web>

To fix add, set session state to an appropriate value in Orchard’s top level web.config. 

        <sessionState mode="InProc" />
