Html.LabelFor error

[Kevin Pratt]

I was trying out nhaml and was converting one of my views that
contained :

<fieldset>
<legend>Fields</legend>

<div class="editor-label">
<%= Html.LabelFor(model => model.UserName) %>
</div>
<div class="editor-field">
<%= Html.EditorFor(model => model.UserName) %>
<%= Html.ValidationMessageFor(model => model.UserName)
%>
</div>

I converted it to :

%fieldset
%legend Fields
.editor-label
= Html.LabelFor(model => model.UserName)
.editor-field
= Html.EditorFor(model => model.UserName)
= Html.ValidationMessageFor(model => model.UserName)


However I'm getting an error message that looks something like:
c:\Documents and Settings\kpratt\Local Settings\Temp\ecjc94rf.
0.cs(56,43) : error CS1061: 'System.Web.Mvc.HtmlHelper' does not
contain a definition for 'LabelFor' and no extension method 'LabelFor'
accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could
be found (are you missing a using directive or an assembly reference?)

I can't seem to use any of the "For" methods.

My web config looks like:
<section name="nhaml"
type="NHaml.Configuration.NHamlConfigurationSection, NHaml" />
<nhaml autoRecompile="true" templateCompiler="CSharp3"
encodeHtml="true">
<assemblies>
<clear />
<add assembly="System, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=B77A5C561934E089" />
</assemblies>
<namespaces>
<clear />
<add namespace="System.Web" />
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Collections" />
<add namespace="System.Collections.Generic" />
</namespaces>
</nhaml>

If this is a limitation is there another way to use the built in
helpers?

Thanks
Kevin

Hi Kevin. The current stable version of NHaml is build against Mvc 1.0.
LabelFor and co are extension from Mvc 2.0. I think there are some
patches for that in the latest trunk. You can grab it form here:

Hi,
I have the same problem. MVC2 methods are not referenced in the
generated views.
