    <p>I am working with an ASP.NET MVC project which was originally started from the <a href="http://codebetter.com/blogs/karlseguin/archive/2009/04/28/presenting-codebetter-canvas.aspx" rel="nofollow noreferrer">CodeBetter.Canvas</a> project - and I'm trying to move to ASP.NET MVC 2. I successfully upgraded my project using <a href="http://weblogs.asp.net/leftslipper/archive/2009/10/19/migrating-asp-net-mvc-1-0-applications-to-asp-net-mvc-2.aspx" rel="nofollow noreferrer">Eilon's upgrade tool</a>, moved to VS2010 (although not yet to .NET 4).</p> <p>The issue I'm having currently is only occurring when using the spark view engine. Here is the relevant bit of code in my View.spark (strongly typed):</p> <pre><code>${Html.EditorFor(e =&gt; e)} </code></pre> <p>The same bit of code <em>works just fine</em> if I use an .aspx view:</p> <pre><code>&lt;%= Html.EditorFor(e =&gt; e) %&gt; </code></pre> <p>The major point here being "EditorFor" is new in ASP.NET MVC 2 and in my project I can use that helper in an ASPX view but not a Spark view.</p> <p>I've tried <a href="https://stackoverflow.com/questions/1261576/asp-net-mvc-2-0-prev-1-and-spark/1264289#1264289">upgrading Spark to use MVC 2</a> (as well as MvcContrib and Ninject), thinking maybe it was one of those that was freaking out - but so far no luck - I'm still seeing the same behavior.</p> <p>Here is the full error message that is thrown from within Spark's BatchCompiler class.</p> <blockquote> <p>Dynamic view compilation failed. (0,0): warning CS1701: Assuming assembly reference 'System.Web.Mvc, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' matches 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35', you may need to supply runtime policy c:\inetpub\wwwroot[myproject]\CodeBetter.Canvas.Web\Views[MyEntity]\View.spark(9,16): error CS1061: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'EditorFor' and no extension method 'EditorFor' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)</p> </blockquote> <p>Here is the Spark related code in my Global.asax:</p> <pre><code>var settings = new SparkSettings() .AddNamespace("System") .AddNamespace("System.Collections.Generic") .AddNamespace("System.Web.Mvc") .AddNamespace("System.Web.Mvc.Html") .AddNamespace("MvcContrib.FluentHtml") .AddNamespace("CodeBetter.Canvas") .AddNamespace("CodeBetter.Canvas.Web") .SetPageBaseType("ApplicationViewPage") .SetAutomaticEncoding(true); #if DEBUG settings.SetDebug(true); #endif var viewFactory = new SparkViewFactory(settings); ViewEngines.Engines.Add(viewFactory); </code></pre> <p>Also, I am referencing System.Web.Mvc.Html in my spark view as mentioned <a href="https://stackoverflow.com/questions/1081650/cannot-use-html-actionlink-in-asp-net-mvc-spark-files">in another SO answer</a>.</p> <pre><code>&lt;use namespace="System.Web.Mvc.Html" /&gt; </code></pre>

    1. COI think the real problem here was that I had mistakenly thought that the version of MVCContrib I was using was using the 2.0.0 version of system.web.mvc.dll - it wasn't! Crap! After updating that, spark, and ninject - it works!

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
