ViewEngine: referencing variables in layout does not appear to work

I have a project that uses two files on disk to simulate an email templating engine:

• Layout.hbs - a layout file containing common markup
• FileReady.hbs - a sample file that references the layout, and contains specific messaging to let a user know that their file is ready to download.

The generated HTML for FileReady.hbs looks like it properly uses the model, but it doesn’t appear to work in Layout.hbs.

This is the C# code I’m using to render the HTML:

// Instantiate handlebars with custom configuration.
var handlebars = Handlebars.Create(new HandlebarsConfiguration
{
    FileSystem = new DiskFileSystem() // Copied from the unit test project
});

// Get the render function for our FileReady view.
var fileReadyRenderer = handlebars.CompileView("Views/EmailTemplates/FileReady.hbs");

// Render the view.
var html = fileReadyRenderer(new
{
    SiteUrl = "http://dev.example.com",
    FileName = "SomeFile.pdf"
});

Layout.hbs contains the following markup:

<div class="footer">
    Please view our <a href="{{SiteUrl}}/privacypolicy/">privacy policy</a>
</div>

And this is the output for that section:

<div class="footer">
    Please view our <a href="/privacypolicy/">privacy policy</a>
</div>

Even though FileReady.hbs properly fills in {{SiteUrl}}, Layout.hbs does not.

Is there a configuration setting or special method to enable this?

I created a sample project here to reproduce the issue:

Thank you.

This fix was released as of 1.9.3!

The only potential issue I see there is the order of the objects - if vm happens to have a property called body, the viewmodel would resolve to that one first and never reach the latter. If we reverse the order, that should ensure the basic behavior is protected. Feel free to go ahead and send a PR in.
