MVC :: RequestValidationException Using CKEDITOR In MVC 2 View?

The CKEDITOR seems to integrate with the TextAreaFor helper but I cannot figure out how to avoid throwing a request validation exception. This is my code from my View page:

<div class="editor-field" >
<%= Html.TextAreaFor(model => model.WebCopy, 10, 80, "" ) %>
<script type="text/javascript">
var CKEDITOR_BASEPATH = '/ckeditor/';
$(function (e) {
// to show the CK editor
CKEDITOR.replaceAll(
{
htmlEncodeOutput : 'true'
});
});
</script>
</div>

I have tried setting <%@ Page ValidateRequest="false" %> and adding <httpRuntime requestValidationMode="2.0" /> to the web.config file.
